उत्तर

The specific heat capacity will change if the scale is °F instead of °C. This is because it is the heat needed to raise the temperature of a unit of the substance by one degree. Since the size of the Fahrenheit degee is not the same as that of the celsium degree, a change of scale will affect the specific heat capacity.
The specific latent heat will not change with a change of scale. This is because this quantity is simply the heat needed to change the state of 1 kg of a substance at its melting/boiling point without any change in temperature. It is thus heat per unit mass and does not depends upon the scale of temperature used.
