Defintion- Heat capacity vs. Specific heat capacity

[Lauren Eng 1G]

In Outline 3 it states "Explain the meanings of heat capacity and specific heat capacity." I thought these two were the same thing. Could someone further explain the difference?

Hey!

A heat capacity is the amount of heat required to raise the temp of an object by 1 degree C. The Specific heat capacity is the heat required to raise the temp 1 gram of a specific substance by 1 degree C.

Specific Heat Capacity is generally the measure that is used and sometimes referred to as just specific heat, but technically there is a difference. Specific heat is the amount of heat required to raise the temperature of an object by 1-degree celsius, whereas specific heat capacity is the amount of heat required to raise 1 g of a substance by 1-degree celsius.

[Christopher Lai 2I]

Heat capacity is just the more general term for describing how much heat energy it would take to raise the temperature of a unit of matter by 1C. Specific heat capacity refers to how much heat energy it would take to raise the temperature of 1g of a substance by 1C. There's also molar heat capacity which is how much heat energy it would take to raise the temperature of 1 mole of a substance by 1K.

Would anyone be able to give an example of a problem where you'd have to use specific heat capacity vs. molar heat capacity?

In lecture, I think Dr.Lavelle specified that the heat capacity means heat required to raise the temperature of an object by 1 degree C, however, once you divide the amount of substance present by the heat capacity, then it becomes specific heat capacity. Another difference is that the general heat capacity is an extensive property, while specific heat capacity is an intensive property.

These practice problems helped me a lot with understanding the basic concepts for solving some specific heat capacity problems.

[Audric Banuelos 1A]

Heat capacity is the heat required to raise the temperature on an object by 1 degree celsius. Heat capacity is an extensive property because it depends on the amount of the substance. On the other hand, specific heat capacity is the required heat to raise the temperature of 1 gram of a substance by 1 degree celsius. This is an intensive property.
