Question

Use the molecular theory of matter to explain briefly why;
A) a gas exerts a pressure on the walls of its container
B) the pressure increase with temperature (assuming that the volume does not change)
C) the pressure inside a balloon increases when it is squashed

Answer 1

Answer:

A)Yes the gas exerts pressure on the wall since it will be having some kinetic energy in that so that it exerts some dE(small energy) pressure on the wall of the container

B) if you keep volume constant and increase the temperature the gas molecules in the container that gets higher kinetic energy than the usual and starts colliding to each other and to the wall as this is increasing pressure also increases

C)yes pressure inside the balloon increases when it is getting squared since volume of the balloon is getting decrease when the pressure increase and pressure is inversely proportional to volume
