• A. The average kinetic energy of a gas is directly proportional to its temperature
• B. At constant tempearture, the volume of a gas increases as the pressure increases
• C. The pressure of a gas is inversely proportional to its volume
• D. The temperature of a gas is directly proportional to its volume
• E. The collisions of molecules with each other are elastic
