Question

EXPLAIN THE sweating mechanism of human body to control the temperature of body

Answer 1

As sweat evaporates it changes its state from liquid to gas. For this it requires heat energy terms as latent heat of evaporation. From where does this sweat gets this heat energy? Well, from the body from where it gets evaporates. And since body gives away heat energy it feels cool.

Answer 2

Answer:

1. When we get sweat,the droplets of sweat evaporates from the surface of our body by absorbing the heat from our body.
2. Thus the particles of liquids (sweat) extract energy from our body and and escapes into the surroundings.
3. As the energy from our body is is lost in the form of heat energy, the body becomes cool and we feel comfortable.
