Boyle's and Charles' Laws

The volume of a gas at 25^ο C is 3.8 L.  What will be the volume of that gas at 57 ^ο C if the pressure is held constant?

• 8.66 L

• 4.21 L

• 6.34 L

• 3.46 L

A sample of oxygen gas in a closed system has a volume of 200 milliliters 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 milliliters.

• 300 milliliters.

• 100 milliliters.

• 200 milliliters.

The volume of a sample of a gas at 273 ^oC is 200 liters. If the volume is decreased to 100 liters at constant pressure, what will be the new temperature of the gas?

• 0 K

• 546 K

• 273 K

• 100 K

For a given sample of a gas, what must remain constant if Boyle's law is to be applied?

• pressure and volume

• pressure and temperature

• volume and amount of gas

• temperature and amount of gas

In BOYLE'S LAW, when Volume increases then Pressure must...

• Increase

• Decrease

A gas at a volume of 4 liters is at a pressure of 2 atm. The volume is changed to 16 Liters, what must the new pressure be?

• 2 atm

• 12 atm

• 10 atm

• 0.5 atm

True or False. Boyle's Law shows the indirect relationship between volume and pressure as temperature remains constant.

• True

• False

True or False. If temperature remains constant, increase in volume will result to an increase in pressure.

• True

• False

True or False. High temperature allows gas particles to move more rapidly, thereby increasing pressure.

• True

• False

Gas particles move in random motion and they will eventually collide with the walls of their containers, these collisions increase pressure.

• True

• False
