The gas pressure inside a container decreases when

• the number of gas molecules is increased.

• the number of gas molecules is decreased.

• the temperature is increased

• the number of molecules is increased and the temperature is increased.

What is the difference between heat and temperature?

• Temperature is the average kinetic energy of the molecules, but heat is the total potential energy of the molecules.

• Temperature is the average kinetic energy of the molecules, but heat is maximum kinetic energy.

• Temperature is the total kinetic energy of the molecules, but heat is the average kinetic energy of the molecules.

• Temperature is the average kinetic energy of the molecules, but heat is the total kinetic energy of the molecules.
