Question

1. A sample of ideal gas at room temperature occupies a volume of 31.0 L at a pressure of 612 torr . If the pressure changes to 3060 torr , with no change in the temperature or moles of gas, what is the new volume, V2 ?

2. If the volume of the original sample in Part A (P1 = 612 torr , V1 = 31.0 L ) changes to 61.0 L , without a change in the temperature or moles of gas molecules, what is the new pressure, P2 ?

3. A sample of ideal gas is in a sealed container. The pressure of the gas is 785 torr , and the temperature is 2 ∘C . If the temperature changes to 86 ∘C with no change in volume or amount of gas, what is the new pressure, P2 , of the gas inside the container?

4. Using the same sample of gas (P1 = 785 torr , T1 = 2 ∘C ), we wish to change the pressure to 7850 torr with no accompanying change in volume or amount of gas. What temperature T2 , in Celsius, is needed to reach this pressure?

5. A sample of gas in a balloon has an initial temperature of 37 ∘C and a volume of 1.86×10³ L . If the temperature changes to 89 ∘C , and there is no change of pressure or amount of gas, what is the new volume, V2 , of the gas?

6. What Celsius temperature, T2 , is required to change the volume of the gas sample in Part A (T1 = 37 ∘C , V1 = 1.86×10³ L ) to a volume of 3.72×10³ L ? Assume no change in pressure or the amount of gas in the balloon.
