Formula of Latent Heat
The latent heat formula is given by,
L = Q / M
Where,
Q = amount of heat
M = mass of the substance
Solved Examples
Example 1
Determine the latent heat of 5 kg substance if the amount of heat for a phase change is 300 k.cal.
Solution:
Given parameters are,
Q = 300 k.cal
M = 5 kg
The formula for latent heat is given by,
L = Q / M
L = 300 / 5
L = 60 k.cal/kg
