The latent heat of vaporization of water...

The latent heat of vaporization of water at its boiling point is `L_(V)`. But water can evaporate at temperatures below the boiling point – for example it evaporates at body temperature when you perspire. Will the energy needed to evaporate unit mass of water at body temperature be more than or less than `L_(V)`?

Text Solution

Verified by Experts

The correct Answer is:
More than `L_(V)`.

A child running a temperature of 101^F is given and antipyrin (i.e. a madicine that lowers fever) which cause an increase in the rate of evaporation of sweat from his body. If the fever is brought down to 98^@F in 20 min., what is the averatge rate of extra evaporation caused, by the drug ? Assume the evaporation mechanism to the only way by which heat is lost. The mass of the child is 30 kg. The specific heat of human body is approximately the same as that of water and latent heat of evaporation of water at that temperature is about 580 cal. g^(-1).
