What is true about specific heat quizlet?
What is true about heat capacity and specific heat? Only specific heat accounts for mass. Which of the following factors is not used in calculating the specific heat of a substance? The amount of heat needed to raise 250 g of a substance by 15 K is 2,930 J.
Why is specific heat more useful than heat capacity?
For example, more energy will be needed to heat a 5 gallon tank of water 1 degree C than would be needed to heat one cup of water by 1 degree C. On the other hand specific heat capacity will be more useful because it is the amount of energy needed to raise the temperature a gram of that object by 1 degree C.
Which statement best describes how mass impacts the specific heat value of a substance?
Explanation: Specific heat is defined as amount of heat per unit mass of substance that is needed in order to increase the temperature of the substance by one degree celsius. Mass of the substance has no effect on specific heat, as it is already a quantity expressed per unit mass.
Which statement describes the relationship between heat capacity and specific heat capacity?
Which statement defines the thermal capacity heat capacity of a solid body?
Explanation: The thermal capacity of a body is the heat necessary to raise the temperature of the body by one degree.” Thermal capacity = mass of body × specific heat.
Which statements are true concerning the energy and specific heat video?
Which of the following is a correct calculation of specific heat capacity?
What are characteristics of heat?
Characteristics of Heat
It has no shape, no mass, no colour, no odour, no volume and no weight. It is an invisible from of energy. The presence of warmth is left only through its effect on matter. It might be transferred from one body to another.
Which units express specific heat?
The symbol for specific heat is cp, with the p subscript referring to the fact that specific heats are measured at constant pressure. The units for specific heat can either be joules per gram per degree (J/goC) or calories per gram per degree (cal/goC).
Why heat is considered as a form of energy?
Yes heat is a form of energy simply because it’s a result of energy conversion and can also be converted to other forms. Remember the old saying that energy cannot be created nor destroyed. If electromagnetic wave reaches infrared region it is sensed as heat energy if sufficient enough.
What is heat How does heat differ from thermal energy?
The difference between heat and thermal energy is that thermal energy is not in the process of being transferred; it is not in transit, but remains as part of the internal energy of the system; heat, on the other hand, is energy in transit, i.e. energy in the process of being transferred from a hotter system.
Which statement best describes how the calorimeter can be used to determine the specific heat capacity of the metal sample?
Which statement best describes how the calorimeter can be used to determine the specific heat capacity of the metal sample? Energy transfers from the metal to the water and calorimeter until they are all at room temperature.
What is the specific heat of a metal?
Specific heat is amount of energy, measured in either joules or calories, needed to raise the temperature of one gram of the substance one degree Celsius. Often applied to metallic elements, specific heat can be used as a basis for comparing energy absorption and transfer.
What does specific heat depend upon quizlet?
Specific heat of a material is dependent on the type of substance, its density of atoms, and mass.
What is specific heat used for?
Specific heat is a measure of how much energy it takes to raise the temperature of a substance. It is the amount of energy (in joules) needed to raise the temperature of 1 gram of the substance by 1 °C. Specific heat is a property that is specific to a given type of matter, and substances vary in their specific heat.
What is the difference between heat capacity and specific heat quizlet?
Heat capacity is the thermal energy, in joules, that an object must gain or lose to cause a temperature change of 1 degree C. Specific heat is the heat capacity per gram of material, the amount of material that must be gained or lost to change the temperature 1 gram of the substance 1 degree C.
What is the specific heat value of water?
Water has a specific heat capacity of 4.186 J/g°C, meaning that it requires 4.186 J of energy (1 calorie) to heat a gram by one degree.
What does specific mean in specific heat capacity?
Specific heat capacity is the amount of heat energy required to raise the temperature of a substance per unit of mass. The specific heat capacity of a material is a physical property. It is also an example of an extensive property since its value is proportional to the size of the system being examined.
Is specific heat the same as specific heat capacity?
The difference between specific heat and heat capacity is the difference of mass in the calculation. Both of them are defined as the amount of energy required to raise the temperature but, in specific heat, the capacity is calculated per unit mass of a substance.
How does heat capacity differ from specific heat capacity?
Heat capacity is the ratio of the amount of heat energy transferred to an object to the resulting increase in its temperature. … Specific heat capacity is a measure of the amount of heat necessary to raise the temperature of one gram of a pure substance by one degree K.

Does specific heat depend on mass?
Specific heat does not depend upon the mass of the substance.
Does molar mass affect specific heat capacity?
Since the molar heat capacity of a substance is the specific heat c times the molar mass of the substance M/N its numerical value is generally smaller than that of the specific heat.
How does heat affect the mass of a substance?
In almost every chemistry and introductory physics textbook you’ll find the answer to this is that temperature has absolutely no effect on mass. In normal situations and to normal precision, mass is completely unchanged when you add energy to a system.
