Chemistry Gas Laws

Q. A cylinder is filled with 10.0 L of gas and a piton is put into it. The initial pressure of the gas is measured to be 159 kPa. The piston is now pulled up, expanding the gas, until the gas has a final volume of 52.0 L. Calculate the final pressure of the gas. Round your answer to 3 significant digits.

Q. An arctic weather balloon is filled with 2.86 L of helium das inside a prep shed. The temperature inside the shed is 15 degrees C. The balloon is then taken outside, where the temperature is -22 degrees C. Calculate the new volume of the balloon. You may assume the pressure on the balloon stays constant at exactly 1 atm. Roud your answer to 3 significant digits.
