A. specific heat
B. latent heat
C. absolute heat
D. relative heat
Answer: Option B
Solution (By Examveda Team)
The heat stored in water vapor is called latent heat. Latent heat is a form of thermal energy that is stored when a substance changes phase, such as from a liquid to a gas.This Question Belongs to Physics GK Chapter Wise >> Heat And Thermodynamics

A black body can absorb radiations of
A. lower wavelengths only
B. intermediate wavelengths only
C. higher wavelengths only
D. all wavelengths
The correct answer is B. Latent heat.
Latent heat is the energy required to change the state of a substance (solid to liquid or liquid to gas) without changing its temperature. In this case, the heat stored in water vapor is latent heat,

The absolute temperature is not significant in thermodynamics usually.
0 degree Celsius equals 273 Kelvin and room temperature generally 27 degree Celsius so in Kelvin it would be 300k
