Define thermal capacity.
Advertisements
Solution
- Heat capacity or thermal capacity is defined as the amount of heat energy required to raise the temperature of a body by 1°C. It is denoted by ‘C’.
- C = Q/t, where C’ is the heat capacity, ‘Q’ is the quantity of heat required and ‘f’ is rise in temperature.
- SI unit of heat capacity is J/K. It is also expressed in cal/°C, kcal/°C or J/°C.
