Question
What do you understand by: (i) Specific heat capacity (ii) Molar heat capacity?
Solution
(i) Specific heat capacity: The specific heat capacity (c), is the quantity of heat required to raise the temperature of one unit mass of a substance by 1°C (or one kelvin). For finding out heat q required to raise the temperature of a sample, we multiply the specific heat capacity of the substance c, by the mass m, and the temperature change, ∆T.

(ii) Molar heat capacity: The molar heat capacity of a substance is its heat capacity for one mole of a substance.

(ii) Molar heat capacity: The molar heat capacity of a substance is its heat capacity for one mole of a substance.
