At lower temperatures and pressures, the latent heat of vaporisation of a refrigerant

A. Decreases

B. Increases

C. Remains same

D. Depends on other factors

Answer: Option B

Solution (By Examveda Team)

Refrigerant with a lower latent heat of vaporization will absorb less energy during evaporation than those with higher hfg.
The temperature for a given pressure at which the gaseous refrigerant begins to condense into a liquid.
