Question

If the m mass of the substance undergoes a change from one state to another, then the amount of heat required for the process is?

Answer 1

Amount of heat required for the process:

• When the mass m of the substance undergoes a change from one state to another, the amount of heat required for the process is given by;

$\mathrm{Q}=\mathrm{m}\times \mathrm{L}$

• Here L is known as the latent heat of the substance.

Hence, If the m mass of the substance undergoes a change from one state to another, then the amount of heat required for the process is called the latent heat of the substance.
