Latent Heat Definition & Meaning

Latent Heat is defined as the amount of heat or energy absorbed or released during a phase change of substance. It can be from liquid to gas or from solid to liquid and vice versa. However, one important thing to be considered regarding the Latent Heat is that the temperature remains constant.

Latent Heat Formula

During the Calculation of Latent Heat a formula can be quite handy and makes your job much simple. Latent Heat Formula is Q = m * L

  • Where m is the mass of the body and its units are kg.
  • L is the Latent Specific Heat and expressed in units kJ/kg
  • Q is the heat absorbed or released based on the direction of transition and its units are kJ

How to Calculate Latent Heat?

Go through the simple measures provided below to determine the latent heat. They are as such

  • Initially, find the the mass of a substance.
  • Next, determine the specific latent heat.
  • Substitute the input parameters in the formula of Latent Heat i.e. Q = m * L
  • Simplify the equation further and evaluate the latent heat easily.


Calculate the latent heat of a 15 kg substance if the amount of heat for transition is 450Kcal.


Given that

Mass of the Substance m = 15kg

Amount of heat for Transition Q = 450Kcal

We know the formula for Latent Heat is Q = m*L

Interchanging the above equation to get the Latent Heat we have the equation L = Q/m

Substituting the input parameters in the above formula we get L = 450/15 = 30KCal/kg

Therfore, the amount of latent heat needed for transition is 30 Kcal/Kg.
