A sample of oxygen gas in a closed system has a volume of 200 L at 600 K. If the pressure is held constant and the temperature is lowered to 300 K, the new volume of the gas will be -

• 400 L.

The kinetic theory states

• Particles won't move if you don't apply energy to it.
• Particles only move in liquids and gases.
• Particles are always in motion.
• At the same temperature the object that has the most mass heats quicker.
