Combined Gas Law Worksheet Display your work! The numerical answers (before rounding for significant digits) are at the bottom – they are just for you to check yourself, I still need to spot all your work. 1. I have an unknown volume of gas at a pressure of 0.5 atm and a temperature of 325 K. If I raise the pressure to 1.2 atm, shrink the temperature to 320 K, and measure the final volume to be 48 liters, what was the initial volume of the gas? 2. A toy balloon has an internal pressure of 1.05 atm and a volume of 5.0 L. If the temperature where the balloon is released is 200 C, what will happen to the volume when the balloon rises to an altitude where the pressure is 0.65 atm and the temperature is –150 C? 3. A small research submarine with a volume of 1.2 x 105 L has an internal pressure of 1.0 atm and an internal temperature of 15° C. If the submarine descends to a depth where the pressure is 150 atm and the temperature is 3 °C, what will the volume of the gas inside be if the hull of the submarine breaks? 4. A gas that has a volume of 28 liters, a temperature of 45 °C, and an unknown pressure has its volume increased to 34 liters and its temp

Problem #1: A 30.0 L sample of nitrogen inside a rigid, metal container at 20.0 °C is placed inside an oven whose temperature is 50.0 °C. The pressure inside the container at 20.0 °C was at 3.00 atm. What is the pressure of the nitrogen after its temperature is increased to 50.0 °C?

Solution:

P1  P2
––– = –––
T1  T2

3.00   x
––– = –––
293   323

Solution technique: cross-multiply and divide.

x = 3.31 atm (to three sig figs)

Note: you will see set ups (especially in gas laws) that simply omit all the units in the answer. If you do that on a homework issue or test, you may get a deduction. It's not laziness on the part of the person writing the solution, it's simply assuming the reader knows what the units are and how they cancel out to depart the final unit.

Many times, you (as the student) are not allowed that luxury.

Problem #2: Determine the pressure transform when a constant volume of gas at 1.00 atm is heated
