Question

A group of students accompanied by their science teacher went trekking. After reaching the top of the hill they felt hungry. The Teacher told them that they would have to bear the hunger as cooking of food is slow and takes a longer time at the top of the hill. The students wanted to known the reason for the above fact. The Teacher explained the reason for the above fact till the food was cooked. Can you predict the explanation given by the teacher?

Answer 1

With the increase in altitude the atmospheric pressure decreases. Boiling point of water is directly proportional to the atmosphere pressure. Hence boiling point of water decreases at the top of a hill and cooking takes a longer period of time.
