Question

On a hot sunny day why do we feel pleasant sitting under a tree?​

Answer 1

Answer:

because of cool shade .....

Answer 2

Answer:

Explanation: we feel cool when seated under a tree because of the photosynthesis process that takes place in plants. During the process of photosynthesis, co2 is absorbed and o2 is released along with water vapour which makes us feel cold and comfortable. Co2 is a greenhouse gas. It heats the environment making us feel uncomfortable. As trees have very less co2 around them, we obviously don't feel hot under a tree. The fact that trees give shade is also considerable coz the shade protects us from direct sunlight,, and still keeps us more comfortable.! :)
