Why does a fluid heat up faster when their is more pressure?

Question

im in grade 10 science i noticed that if i was to cook soup in my home the boiling point would be obviously 100 degrees Celsius, but if i was in an area with high pressure it would heat up faster? why is this? does it have something to do with heat energy? Kinetic energy?

Answer 1

because when there is more pressure, the molecules are closer together, causing them to bump into each other more, AKA heating up faster.

Answer 2

Yes. Pressure is directly proportional with temperature.

Ideal Gas Law PV = nRT

P = pressure

V = volume

n = numer of mole of gas (measure for amount of gas, can also be mass)

R = universal gas constent

T =  Temperature

so from the above equation, you will se as temperature increasure,

1. pressure will increasure

2. volume decrease

Answer 3

It would heat up faster because there is more air pressure, and the pressure helps keep the heat closer. So the heat goes away slower. However, when there's low pressure, there's nothing "stopping" the heat from escaping, so it cools faster.
