What is the relationship between pressure and volume of a gas at constant temperature?

The pressure of a gas in a container is 1.23 atm and occupies a volume of 1.5 L. If the original volume is doubled at constant temperature, what would happen to the pressure?

Three different balloons under identical conditions only differ in the identity of the gas contained inside. One contains 1 mole of helium, another contains 1 mole of neon, and the other contains 1 mole of argon. How can the three balloons be distinguished?

Suppose your car is equipped with tire pressure monitoring system (TPMS) and the tire pressure is 34.0 psi on a 98 °F day in California. You decided to take a road trip to Alaska where the temperature drops to 20 °F. As you arrived in Alaska, you noticed that the tire pressure monitoring system alert light is illuminated. Why did this happen?

Helium gas is collected over water at 333 K. The pressure of the gas above the water is measured. What additional piece of information is needed to determine the amount of helium collected?

Which of the following will result in the largest deviations from ideal gas behavior?

Which statement accurately depicts what happens to water on the molecular level in a tea pot when it begins to boil?
