Chpt 14.3: Behavior of Gases

Boyle's law states that the pressure of a gas is inversely proportional to its volume, if the temperature and amount of gas remain constant. Which of the following equations represents Boyle's law?

• P1V1 = P2V2 / T

• P1V1 = P2V2

• P1V1 = P2V2 * T

• P1V1 = P2V2 + nRT

If the volume of a gas is reduced to half of its original volume, what happens to the pressure of the gas according to Boyle's law?

• The pressure of the gas remains the same

• The pressure of the gas decreases

• The pressure of the gas becomes zero

• The pressure of the gas increases

A gas at a pressure of 2 atm has a volume of 4 L. If the volume is decreased to 2 L, what will be the new pressure of the gas according to Boyle's law?

• 1 atm

• 6 atm

• 4 atm

• 8 atm

According to Charles's law, what happens to the volume of a gas if its temperature is doubled, assuming the pressure and amount of gas remain constant?

• The volume of the gas will be halved.

• The volume of the gas will remain the same.

• The volume of the gas will triple.

• The volume of the gas will double.

Absolute Zero is the temperature at which there is no heat energy; this corresponds to -273.15^oC on the Celsius scale.What are absolute zero and the freezing point of water on the Kelvin (K) scale.

• 0^oK and 100^oK

• 0^oK and 273.15^oK

• 32^oC and 212^oC

• The correct answer is not given

If the volume of a gas is 3 L at a temperature of 300 K, what will be the new volume of the gas if the temperature is increased to 600 K according to Charles's law?

• 6 L

• 2 L

• 4 L

• 9 L

Charles's law states that the volume of a gas is directly proportional to its temperature, if the pressure and amount of gas remain constant. Which of the following equations represents Charles's law?

• V1+T1 = V2+T2

• V1-T1 = V2-T2

• V1*T1 = V2*T2

• V1/T1 = V2/T2

A gas at a volume of 5 L has a temperature of 200 K. If the temperature is increased to 400 K, what will be the new volume of the gas according to Charles's law?

• 15 L

• 8 L

• 10 L

• 3 L

If the volume of a gas is tripled, what happens to the temperature of the gas according to Charles's law?

• The temperature of the gas will also triple.

• The temperature of the gas will decrease

• The temperature of the gas will remain the same

• The temperature of the gas will double

A gas at a volume of 2 L has a temperature of 300 K. If the volume is increased to 6 L, what will be the new temperature of the gas according to Charles's law?

• 450 K

• 600 K

• 900 K

• 750 K
