Gas Law Practice Problems

1 A sample of gas has an initial volume of 25 L and an initial pressure of 3.5 kPa. If the pressure changes to 1.3 kPa, find the new volume, assuming that the temperature remains constant.

2 A sample of neon is at 189K and 123 kPa. If the pressure changes to 145 kPa and the volume remains constant, find the new temperature, in K.

3 A child has a balloon with a volume of 1.8 liters. The temperature of the balloon when it was filled was 293 K. If the child was to let go of the balloon and it rose 3 kilometers into the sky where the temperature is 263 K, what would the new volume of the balloon be?

4 A sample of sulfur dioxide (SO 2 ) is initially at a temperature of 133 K, a volume of 20 L, and a pressure of 850 kPa. If the volume stays the same and the temperature increases to 181K, find the new pressure.

5 A small balloon is inflated with helium at 102 kPa to a volume of 2.12 L. According to the balloon's manufacturer, if the balloon is stretched to a volume of 4.25 L, the balloon will pop. If the balloon were released, at what pressure would the balloon pop? Assume constant temperature throughout.
