Question

Why does hot air come out when we say haaa and cold air comes out when we say hooo?

Answer 1

hey friend , here is your answer:

when we say haaa or hooo the we exhale the air that we have inhaled

when we say hoooo our mouth (opening where the air escapes) is some what closed compared to when we say haaaa

thus this small space will compress the air that we exhale and thus very very few water molecules (moisture) is compressed and this results in the cool air due to the presence of condensed moisture.

but this compression is comparitively low when we say haaa thus it is comparitively hot
