What is the mass of a material, whose specific heat capacity is 400 J/(kg °C) for a rise in temperature from 15°C to 25°C, when heat received is 20 kJ?

The amount of heat required to change from liquid state to gaseous state without rise in its temperature is called:

The specific latent heat of vaporization of a substance is the quantity of heat needed to change unit mass from

What changes will the volume of water show if the temperature is lowered from 9° C to 3° C :

The amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius is called its:

The ratio of the amount of heat absorbed by a substance to the corresponding rise in temperature is called its:
