Question

we sweat more on a humid day give reason

Answer 1

That is because on a humid day, moisture content in air is more. So there's already a lot of water droplets floating in air. Thus air, naturally, loses its capability to take in any more water. So your skin stays sweaty. Actually no don't sweat "more", but it's just that the sweat stays on your skin instead of diffusing in air ☀️

Answer 2

Answer : - On dry day , sweat evaporate quickly , which means it also carries away heat faster . On humid days , when their air is already saturated with water , sweat is evaporates more slowly .
