Question

Given below are two statements, one is labelled as Assertion (A) and the other as Reason (R): Assertion (A): Evaporation of sweat from human skin dissipates body heat. Reason (R): High humidity on a hot day increases discomfort. Select the correct answer from the code given below: Code:

PYQPulse · Accepted Answer

Both (A) and (R) are true, but (R) is not the correct explanation of (A)

PYQPulse · Answer

Explanation: Assertion (A) is true because evaporation of sweat from the skin surface absorbs latent heat of vaporization , which helps cool the body and maintain body temperature. Reason (R) is also true because high humidity reduces the rate of evaporation of sweat , causing less cooling and hence more discomfort .
