Q: Why do we perspire more in a crowded train standing at a railway platform and feel more comfortable when the train starts moving ?

Sol: Due to breathing of passengers of the crowded train , the air in the compartment gets almost saturated . Hence , sweat does not evaporate and we perspire . When the train starts moving , evaporation sets in due to the supply of fresh air and we feel comfortable .
