Question

during constant temperature, we feel colder on a day when the relative humidity will be......

Please give explanations for ur answer.

Answer 1

I think LESS because the rate of evaporation depends upon the humidity. Higher the humidity, low the rate of evaporation and vice versa. If the humidity is low, then the rate of evaporation of sweat from the body will increase. As the sweat will evaporate, it will take away the some part of the body heat as latent heat thereby making us feel cool. So, during constant temperature, we feel colder ona day when the relative humidity will be LESS. If the humidity is more, then the rate of evaporation will decrease and the sweat will not evaporate, making us feel uncomfortable ( unless u r counting to sit in the fridge whole day long! :-) ) rather than cool.
