COMBINED GAS LAW WORKSHEET 3RD QUARTER 2013-2014


Combined Gas Law Problems


1)         If I initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 K, and then I raise the pressure to 14 atm and increase the temperature to 300 K, what is the new volume of the gas?
29.57 L

2)         A gas takes up a volume of 17 liters, has a pressure of 2.3 atm, and a temperature of 299 K.  If I raise the temperature to 350 K and lower the pressure to 1.5 atm, what is the new volume of the gas?
30.5 L

3)         A gas that has a volume of 28 liters, a temperature of 45 0C, and an unknown pressure has its volume increased to 34 liters and its temperature decreased to 35 0C.  If I measure the pressure after the change to be 2.0 atm, what was the original pressure of the gas?
2.5 atm

4)         A gas has a temperature of 14 0C, and a volume of 4.5 liters.  If the temperature is raised to 29 0C and the pressure is not changed, what is the new volume of the gas?
4.7 L

5)         If I have 17 liters of gas at a temperature of 67 0C and a pressure of 88.89 atm, what will be the pressure of the gas if I raise the temperature to 94 0C and decrease the volume to 12 liters?
135.9 atm

6)         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, decrease the temperature to 320 K, and measure the final volume to be 48 liters, what was the initial volume of the gas?
117 L

7)         If I have 21 liters of gas held at a pressure of 78 atm and a temperature of 900 K, what will be the volume of the gas if I decrease the pressure to 45 atm and decrease the temperature to 750 K?
30.33 L
 
8)         If I have 2.9 L of gas at a pressure of 5 atm and a temperature of 50 0C, what will be the temperature of the gas if I decrease the volume of the gas to 2.4 L and decrease the pressure to 3 atm?
160 K

9)         I have an unknown volume of gas held at a temperature of 115 K in a container with a pressure of 60 atm.  If by increasing the temperature to 225 K and decreasing the pressure to 30 atm causes the volume of the gas to be 29 liters, how many liters of gas did I start with?
7.41 L
