Question 6c

Give reasons:

It is difficult to cook in hills as compared to plains.

Answer

The boiling point of water decreases with a decrease in pressure. Therefore, water boils at a lower temperature (i.e., less than 100°C) in hilly areas where the atmospheric pressure is lower as compared to the plains. Due to this it takes a longer time to cook food making cooking difficult in hills.
