4. A sample of 25L of NH3 gas at 10 °C is heated at constant pressure until it fills a volume of 50L. What is the new temperature in °C?
5. A 600ml balloon is filled with helium at 700mm Hg barometric pressure. The balloon is
released and climbs to an altitude where the barometric pressure is 400mm Hg. What
will the volume of the balloon be if, during the ascent, the temperature drops from 24 to
5°C?
6. The pressure inside of a sealed container is 645.0 torr at a temperature of 25 °C. At
what temperature will the container have a pressure of 2.21 atm?
7. A balloon has a volume of 650. mL when it contains 0.250 mol of a gas. If 0.123 mol of
the gas is released from the balloon, what is the new volume?
8. In an autoclave, a constant amount of steam is generated at a constant volume. Under
1.00 atm pressure the steam temperature is 100°C. What pressure setting should be
used to obtain a 165°C steam temperature for the sterilization of surgical instruments?
