5. Why does a desert cooler cool
better on a hot dry day?
2. How does the water kept in an
earthen pot (matka) become cool
during summer?
Why does our palm feel cold
when we put some acetone or
petrol or perfume on it?​

Answer 1

Answer:

1. due to low humidity and high temperature, rate of evaporation increases on a hot dry day . so, a desert cooler cools better on a hot dry day.

2.an earthen pot have many fine pores. Water molecules come on its surface by heat from inner water and evaporate. so water inside the pot becomes cool.

3.because particles of perfume , acetone or petrolbtake heat from our palm and evaporate ...it cause cooling of our palm...

hope this will help uh...

3.Acetone,petrol and perfume are volatile substance that gets evaporated when they come in contact with air Evaporation is facilitated as it uses energy from the palm hence leaving a cooling effect on our palms.
