Question

Relation between latent heat boiling pint and height

Answer 1

hello dear


The heat energy (enthalpy of evaporation) needed by the water at higher pressure to change it into steam is actually less than the heat energy required at atmospheric pressure. This is because the specific enthalpy of evaporation decreases as the steam pressure increases. The specific volume also decreases with increasing pressure, the amount of heat energy transferred in the same volume actually increases with steam pressure.



hope it will help u
