Heat Capacity

What is the difference between Specific heat capacity and molar heat capacity?

[Kayla Maldonado 1C]

Molar heat capacity is the amount of heat needed to raise the temperature of one mole of a pure substance by one degree Kelvin. Specific heat capacity is the amount of heat necessary to raise the temperature of one gram of a pure substance by one degree Kelvin.

Molar heat capacity I think is the heat needed to raise the temperature of one mole of a substance, while specific heat capacity is more of an intrinsic value to identities of substances- like, specific heat capacity is unique to the identity of the substance. So no matter how much you have of it, you need that temperature.

So, can you convert between specific and molar heat capacity?

[DLee_1L]

YEs! Specific heat is J/(kg*K) and molar specific heat is J/(kg*m) so you would need to get the molar mass of the substance and do some dimensional analysis.

Does this mean that Specific heat capacity will always be less than molar heat capacity since it's 1 gram vs. 1 mole?

Molar heat capacity is the amount of heat needed to raise the temperature of one mole of a pure substance by one degree Kelvin. Specific heat capacity is the amount of heat necessary to raise the temperature of one gram of a pure substance by one degree Kelvin.
