Gas has no fixed shape and conforms to the volume of its container. A liquid has a distinct volume but assumes the shape of its container.
What state of matter assumes the volume and shape of its container?
Gases have the following characteristics: no definite shape (takes the shape of its container) no definite volume. particles move in random motion with little or no attraction to each other.
In which states does matter change shape in different containers?
both liquids and gases take the shape of their containers. Only liquids meet both requirements.
In the gas phase the molecular forces are very weak. A gas fills its container, taking both the shape and the volume of the container. Liquids and gases are called fluids because they can be made to flow, or move.
Why do liquid and gases have indefinite shape and assume the shape of the container?
In a liquid, the particles are still in close contact, so liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.
What is the shape of a gas in a container?
Gases have the following characteristics: No definite shape (takes the shape of its container). No definite volume. Particles move in random motion with little or no attraction to each other.
What happens to the volume of gases when placed in different containers?
Because gases expand to fill their containers, it is safe to assume that the volume of a gas is equal to the volume of its container. The difference between the volume of a gas and the volume of the liquid or solid from which it forms can be illustrated with the following examples.
Why gases do not assume definite shape it is because the?
Gases do not have a definite shape or volume because the molecules in gases are very loosely packed, they have large intermolecular spaces and hence they move around. The force of attraction between molecules is also very less, as a result gases acquire any shape or any volume.
Does gas have a fixed volume?
Gas is a state of matter that has no fixed shape and no fixed volume. Gases have a lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between particles, which have a lot of kinetic energy and aren’t particularly attracted to one another.
What determines the volume of a gas?
The volume of a gas is determined by the volume of the container it is in. Gases take the shape of their container and the volume of the container….
Why do gases expand to fill their container?
Answer: Gases are in rapid motion, and they undergo elastic collisions with each other and the walls of the container; that is, momentum and energy is transfered not lost during collisions. Gases expand spontaneously to fill any container (rapid motion).
Why do liquids assume the shape of their container?
The forces between liquid particles are weaker than the forces between solid particles. This means that liquid particles are further apart and can move about more easily. Since the particles can move, the liquid can flow and take the shape of its container.
Why do gases do not have fixed shape and volume?
Gases do not have a fixed shape or volume so that the particles are freely moving. They do not have a fixed position or spaces between them.
Do the gases have a definite shape and a fixed volume?
In gases, molecules are loosely packed. The force of attraction between the molecules of gases is least as compared to solids and liquids. The kinetic energies between the molecules is high enough to break away from any boundaries and they move randomly. Thus, gases do not have definite shape and volume.
Does gas occupy the space of a container?
In addition to solids and liquids, gases are also a physical state in which matter can occur. All gases have weight. Unlike solids and liquids, gases will occupy the entire container that encloses them.
What retains its shape regardless of the shape of the container?
It retains its shape regardless of the shape of the container. plasma Particles move freely but do not separate from neighboring particles. gas This state, in which the particles are at extremely high temperatures, is rarely found on Earth. liquid It expands to fill the volume of the container.
What takes the shape of the container but not the size?
Solid, liquid and gas are the most common forms (or states) of matter. A liquid has definite size (or volume) but indefinite shape. For example, milk is liquid. It takes the shape of its container but its volume remains the same irrespective of the size of the container.
Does gas have a definite shape?
A gas has neither a definite shape nor a definite volume. Like liquids, gases are fluids. The particles in a gas can move around one another freely. If a gas is released in a closed container, the gas particles will move in all directions and spread apart as they fill the container.
What determines the shape and volume of a gas?
What determines the shape and volume of a gas inside a container? The shape and volume of a gas are the same as those of their container. Use what you know about particles in a gas to explain why a gas has no definite shape and no definite volume.
Does gas have mass and volume?
Gases do not have a definite shape, mass, or volume.
Which one of the following changes would cause the volume of a gas to double assuming moles were held constant?
Which one of the following changes would cause the pressure of a gas to double assuming volume and moles were held constant? Increasing the temperature from 200 K to 400 K.
What is meant by volume of gas?
Related Definitions Gas volume means the volume of carbon dioxide gas, expressed at standard conditions (0oC and 1 atmosphere of pressure) dissolved in an equal volume of liquid.
How are the three states related to size and shape?
Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter adapts to the shape of its container but varies only slightly in volume; and gas is the state in which matter expands to occupy the volume and shape of its container.
Do gases fill their container uniformly?
Unlike liquids or solids, gases occupy their containers uniformly and completely. Because molecules in a gas are far apart, it is easier to compress a gas than it is to compress a liquid.
Why can only gases be compressed?
Gases will compress more easily than solids or liquids because there is so much space between the gas molecules.
Do liquids take the shape of their container?
Liquids will flow and fill the lowest portion of a container, taking on the shape of the container but not changing in volume. The limited amount of space between particles means that liquids have only very limited compressibility.
Why do solids have a fixed shape Why do gases follow the shape of the container they are in?
Solids have a fixed shape and a fixed size. The particles are very close together and held in place by strong forces (bonds). Their particles cannot move around, but they do vibrate. Because the particles cannot move around, a solid has a fixed shape.
How does the motion of particles in a gas change as the gas cools?
As a gas cools, its particles slow down. When particles move slowly enough for their attractions to bring them together, droplets of liquid form. This process, which is the opposite of vaporization, is called condensation. As a gas condenses to a liquid, it releases the thermal energy it absorbed to become a gas.
Have a definite shape and volume do not have a definite volume or shape have a definite volume but the shape may change?
A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape. The change from solid to liquid usually does not significantly change the volume of a substance.
Is the shape of a gas definite or indefinite?
Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume either. The change from solid to liquid usually does not significantly change the volume of a substance.
Does air have shape?
Air is a gas. Like all gases, air does not have its own shape. It takes the shape of the container it is in. Air occupies the greatest possible space.
Are substances that flow and keep the shape of the container?
liquid: A substance that flows and keeps no definite shape because its molecules are loosely packed and constantly moving. It takes the shape of its container but maintains constant volume.
What determines the shape and volume of a gas inside a container Why?
The volume and shape of gas is determined by the volume and shape of container it is in. Gas has no definite volume or shape so it takes the shape amd volume of the container in which it is kept. The volume of a gas is determined by the volume of the container it is in.
Which of the following takes the shape of the container because the particles are able to move freely to all parts of the container?
freezing melting. The particles in a liquid are separated by spaces that are large enough to allow the particles to slide past each other. A takes the shape of its container because the particles can move around more freely than they can in a solid. They are held close together, however.
What happens to a gas in a container when it is heated?
When gases in containers are heated, their molecules increase in average speed. This means that they exert a greater force when they collide with the container walls, and also collide with the walls more frequently. The gas is therefore under greater pressure when its temperature is higher.
Do gases have masses?
Gases have mass. The space between gas particles is empty. Gases can be formed as products in chemical reactions. Gas particles can form bonds between them under certain conditions.
Does gas have color?
Gases, like other forms of matter, have physical properties such as color, odor, and taste. In general, gases tend to be colorless and odorless, although some important exceptions exist. Also, most gases are transparent: that is, it is possible to see objects through them rather clearly.
