1. A weather balloon is filled with 15.0 L of helium gas at 25 °C and has a pressure of 685 mmHg. What is the final pressure, in mmHg, of this balloon in the upper atmosphere when the temperature drops to -35 °C and the volume becomes 34.0 L? a) Which two gas laws can be combined to solve this problem? Why? b) Write an expression showing how the two laws you mentioned in part a) can be combined to solve for P2? c) Solve for P2. Show your work. Recall that temperature must always be in Kelvin (K).

A sample of an ideal gas initially has a pressure of 0.775 atm at a temperature of 21.5°C. If the temperature of the gas increases to 97.5°C while volume is kept constant, what is the new pressure of the gas?
A sample of oxygen gas at 301 K and 2.02 atm occupies a volume of 1.82 L. If the gas is allowed to expand to a larger volume, while at the same time it is cooled to a lower temperature, the final gas pressure will be lower than 2.02 atm. O will be higher than 2.02 atm. could be higher or lower than 2.02 atm depending on the final volume and temperature.
