Question

Consider 4.30 L of a gas at 365 mmHg and 20. ∘C . If the
container is compressed to 2.20 L and the temperature is increased
to 34 ∘C , what is the new pressure, *P*2, inside the
container? Assume no change in the amount of gas inside the
cylinder.

Express your answer with the appropriate units.

Answer #1

Part A
Consider 4.30 L of a gas at 365 mmHg and 20. ∘C . If the
container is compressed to 2.70 L and the temperature is increased
to 30. ∘C, what is the new pressure, P2, inside the
container? Assume no change in the amount of gas inside the
cylinder.
Express your answer with the appropriate units.
Part B
A cylinder, with a piston pressing down with a constant
pressure, is filled with 2.00 moles of a gas (n1),...

Consider 4.30 L of a gas at 365 mmHg and 20. ∘C . If the
container is compressed to 2.90 L and the temperature is increased
to 32 ∘C , what is the new pressure, P2, inside the container?
Assume no change in the amount of gas inside the cylinder.

A. A very flexible helium-filled balloon is released from the
ground into the air at 20. ∘C. The initial volume of the balloon is
5.00 L, and the pressure is 760. mmHg. The balloon ascends to an
altitude of 20 km, where the pressure is 76.0 mmHg and the
temperature is −50. ∘C. What is the new volume, V2, of the balloon
in liters, assuming it doesn't break or leak? Express your answer
with the appropriate units.

All pressure–volume–temperature relationships for gases can be
combined into a single relationship known as the combined gas
law. This expression can be used when looking at the effect of
changes in two of these variables on the third as long as the
amount of gas (number of moles) remains constant. To use the
combined gas law properly, you must always express the temperatures
in kelvins. The combined gas law can be represented as follows:
P1V1/T1=P2V2/T2

1. scuba diver 40 ft below the ocean surface inhales 45.0 mL of
compressed air from a scuba tank at a pressure of 2.90 atm and a
temperature of 8 ∘ C . What is the final pressure of the air, in
atmospheres, in the lungs when the gas expands to 145.0 mL at a
body temperature of 37 ∘ C , and the amount of gas does not
change?

Part A A sample of ideal gas is in a sealed container. The
pressure of the gas is 725 torr , and the temperature is 18 ∘C . If
the temperature changes to 75 ∘C with no change in volume or amount
of gas, what is the new pressure, P2, of the gas inside the
container? Express your answer with the appropriate units.
Part B Using the same sample of gas (P1 = 725 torr , T1 = 18 ∘C...

A) A syringe containing 1.25 mL of oxygen gas is cooled from
90.3 ∘C to 0.9 ∘C. What is the final volume Vf of oxygen
gas?
B) What is its volume after an
additional 0.30 mol of gas is added to the cylinder? (Assume
constant temperature and pressure.) Express your answer to three significant
figures.
C) What is the pressure in a 12.9
L cylinder filled with 0.425 mol of nitrogen gas at a temperature
of 300 K ?
D)...

Part A
A sample of ideal gas at room temperature occupies a volume of
27.0 L at a pressure of 202 torr . If the pressure changes to 1010
torr , with no change in the temperature or moles of gas, what is
the new volume, V2?
Express your answer with the appropriate units.
Part B
If the volume of the original sample in Part A (P1 =
202 torr , V1 = 27.0 L ) changes to 60.0 L...

a gas volume with a volume of 4.0 L is in a closed
container. indicate the changes ( increase, decrease, does not
change) in its pressure that must have occurred of the volume
