Question

Why do people feel pleasant sitting under a tree on a hot day??

Answer 1

In summers when we sit under a tree itz transpiration rate increases which makes the tree and it's atmosphere pleasant. When the wind blows the branches and leaves move to increases the rate of wind speed which is directly proportional to evaporation. After getting the blowing wind, the sweat from our body evaporates away absorbing the body heat equal to the latent heat of vaporization from our body making us COOL!!

Answer 2

The most obvious way trees cool the air is by shading. Reducing the amount of sunlight striking buildings and pavement reduces the amount of energy that is absorbed and re-radiated into the air.So,when we sit or stand under a tree we don't feel too warm.
