a 5.50 L volume of gas has a pressure of 1.50 atm at 25deg
celcius. What is the pressure if the volume decreases to 4.25 L and
the temperature decreases to 0deg celcius?
Part A) A sample of a gas at 25°C and 1.0 atm
pressure has a volume of 2.5 L. The container is allowed to expand
until the pressure is 0.85 atm and the temperature is 15°C. The
final volume of the gas is __________ L.
Part B) A reaction is carried out that produces
hydrogen gas. The gas is collected in an inverted beaker over water
at 25 oC. The vapor pressure of water at 25
oC is 23.78 mmHg....

A sample of an ideal gas at 1.00 atm and a volume of 1.46 L was
placed in a weighted balloon and dropped into the ocean. As the
sample descended, the water pressure compressed the balloon and
reduced its volume. When the pressure had increased to 10.0 atm,
what was the volume of the sample? Assume that the temperature was
held constant.
A sample of an ideal gas at 1.00 atm and a volume of 1.02 L was
placed in a weighted balloon and dropped into the ocean. As the
sample descended, the water pressure compressed the balloon and
reduced its volume. When the pressure had increased to 45.0 atm,
what was the volume of the sample? Assume that the temperature was
held constant.
A sample of helium gas has a volume of 5.30 L at a pressure of
