Answer:
Latent heat is the heat required to convert a solid into a liquid or vapour phase, or a liquid into a vapour phase. According to the different phase, it has different names like the heat of condensation, the heat of vaporization etc. The amount of heat energy absorbed or released for a phase change is known as latent heat.
The latent heat formula is given by,
L = Q / M
Where, Q = amount of heat , M = mass of the substance
Explanation:
Example 1
Determine the latent heat of 5kg 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
Formula for latent heat is given by,
L = Q / M
L = 300 / 5
L = 60 k.cal/kg
