Heat Capacity vs Specific Heat Capacity

[torialmquist1F]

Can someone clarify the difference between Heat Capacity and Specific Heat Capacity and how they relate to extensive and intensive properties?

[Gurshaan Nagra 2F]

Dr. Lavelle mentioned in lecture that the heat required to raise the temp of an object by 1 degree Celsius is the heat capacity. This is an extensive property because the heat required depends on the amount of substance. The specify heat capacity is the heat required to raise 1 gram of a substance 1 degree Celsius. This becomes an intensive property because it doesn't rely on the amount of substance like regular heat capacity did.

[Niyanta Joshi 1F]

Heat Capacity is the ratio of heat supplied/absorbed to the corresponding rise in the temperature; in other words it is the amount of heat required to raise the temperature of a substance by 1 degree C. But this does not tell us how much mass of the substance we are measuring. Heat capacity is an extensive property because larger the sample, the more heat required.

Specific heat capacity is the amount of heat required to raise the temperature of 1 gram or 1 mole of substance by 1 degree celsius. It is the heat capacity divided by the grams of the substance. It is specifically for 1 gram or 1 mole of the substance, so how much substance is present does not really affect its value; so it's intensive.
