Heat Capacities

Postby Faizal_Mamani_1F » Sun Jan 15, 2017 2:49 pm

What's the difference between specific heat capacity and molar heat capacity?
-Thanks

The specific heat capacity is measured in grams or kilograms, as opposed to the molar heat capacity which is measured in moles.

Specific heat capacity refers to the amount of energy required to raise the temperature of 1 kg of the substance by 1 degree celsius while molar heat capacity refers to the amount of heat to required to raise the temperature of 1 mole to do the same. Overall, the difference would be mass versus mole being change.

Specific heat capacity is the heat required to raise the temperature of 1g by 1 degree celsius and molar heat capacity is the heat required to raise the temperature of 1 mole by 1 degree celsius. The difference is that one is measured in J/mol and the other is J/g or kJ depending on what information is given. To determine between the two you must identify the type of substance that the heat capacity is dividing with.
