Question 3 Page 10 - Chapter 1 Class 9 - Matter In Our Surroundings

Why does our palm feel cold when we put some acetone or petrol or perfume on it?

 

Answer

Acetone, perfume and petrol are volatile substances , i.e., substances which turn into vapours very easily. 

Hence, when we put either of the substances on our palm, it immediately takes heat from our palm and evaporates

Since some amount of heat is suddenly taken from our palm , the palm feels cold.
