Question

how does perspiration help keeping our body temperature at 37°C even if the temperature of the surroundings is 45°C​

Answer 1

IT IS DUE TO EVAPORATION

EVAPORATION CAUSES COOLING

SO WHEN BODY IS SWEATING THE SWEAT EVAPORATES DUE TO OUTSIDE TEMPERATURE AND HELPS IN COOLING YOUR BODY AND THEREFORE BODY TEMPERATURE IS MAINTAINED

HOPE IT HELPS YOU
