A student says that the pressure of a gas increases when it is heated because the molecules collide with each other more often. Which statement explains why the student is wrong?
The molecules of a hot gas do not collide with each other at all.
The molecules of a gas lose energy every time that they collide.
Heating a gas does not change how often the molecules collide.
Pressure is caused by collisions of molecules with the container walls.
