Information - Named Gas Laws
1. Boyle's law states that as pressure changes, the container volume changes inversely when the number of moles of gas and the temperature are held constant.
2. Charles's law states that as temperature changes, the volume changes proportionally when the pressure and number of moles of gas are held constant.
3. Avogadro's law states that as number of moles changes, the volume changes proportionally when the pressure and the temperature are held constant.
4. Gay-Lussac's law states that the pressure exerted by a gas on its container is proportional to it absolute temperature when the volume and number of moles of gas are held constant.
Assuming gas molecules in a container with a movable end (a piston), what effect will each of following changes have on the specified variable?
The effect on pressure when more gas molecules are added with the volume and temperature held constant.
The effect on pressure when the temperature is increased with the volume and number of molecules of gas held constant.
The effect on pressure when the volume is increased with the temperature and number of molecules of gas held constant.
The effect on volume when the number of molecules of gas is increased with the pressure and temperature held constant.
The effect on volume when the temperature is decreased with the pressure and number of moles of gas held constant.

- A. B. C.The effect on pressure when the volume is increased with the temperature and number of molecules of gas held constant.
- A. B. C.The effect on volume when the number of molecules of gas is increased with the pressure and temperature held constant.
- A. B. C.The effect on volume when the temperature is decreased with the pressure and number of moles of gas held constant.
A.Increase.
B.None.
C.Decrease.
Explanation / Answer
1) A - pressure increases with adding more gas molecules ( no of collision increases)
2) B- pressure increases with increase in temperature( Gay- Lussac law)
3) C - pressure decreases with increase in volume ( Boyles law)
4) A - volume will increase with increase in no of moles ( Avogadro's law)
5) C - volume will decrease with decrease in temperature.
