Physics It takes much longer to cook food in the hills than in the plains, because

in the hills the atmospheric density is low and therefore a lot of heat is lost to the atmosphere
in the hills the humidity is high and therefore a lot of heat is absorbed by the atmosphere leaving very little heat for cooking
n the hills the atmospheric pressure is lower than that in the plains and therefore water boils at a temperature lower than 100oC causing an increase in cooking time
due to low atmospheric pressure on the hills, the water boils at a temperature higher than 100oC and therefore water takes longer to boil

Physics A person can jump higher on the moon's surface than on the earth because :

The moon is cooler than earth
The moon has no atmosphere
The acceleration due to gravity in moon is smaller than that on the earth.
The moon's surface is rough
