Let the mass of the body be ‘m’ and its specific heat capacity be ‘*’. It t°C is the rise in its temperature, then heat taken up by the body is calculated as below:
Since ‘’ is the specific heat capacity of the body which means that the unit mass of the body for a rise of 1°C takes up ‘’ amount of heat.
∴ Mass ‘m’ of the body for a rise of t°C will need heat
= m × * × t
= Mass of the body × Its specific heat × Rise in the temperature
= mst joule.
