Question

Which one term of the kinetic molecular theory is correct. 1. Pressure of a gas is directly proportional to volume. Volume is inversely proportional to temperature. If the temperature decreases, the average kinetic energy of the gas molecules increases and the pressure increases. 2. Pressure of a gas is directly proportional to the amount of gas. The amount of gas is directly proportional to the volume. If the temperature decreases, the average kinetic energy of the gas molecules increases and the pressure increases. This can cause the airbag to burst and it is very dangerous. 3. Pressure of a gas is inversely proportional to temperature. If the temperature decreases, the average kinetic energy of the gas molecules increases and the pressure increases. 4. Pressure of a gas is directly proportional to temperature. If the temperature decreases, the average kinetic energy of the gas molecules decreases and the pressure decrease.
