Gas Quizzes & Trivia
Quiz on gas laws # 1 includes questions on Boyle's Law. Charles' Law, Lussac's Law, and the Combined Gas Law. Identify the law you need to solve the problem and solve the problem. Use classroom rules for rounding and include units in your answer. Example: If 6 liters of a gas at 2. 0 atm iscompress the gas to have a new volume of 5 liters, what is the new pressure? This is a Boyle's Law Problem so P1V1 = P2V2(2. 0)(6) = (P2)(5)P2 = 2. 4Express the answer as 2. 4 atmNote rounding is important numbers greater than 1 are rounded to the tenths place (1 = 1. 0, 5. 85= 5. 9 etc. . . ) and numbers less than 1 are rounded to one place after the first non zero (0. 000567 = 0. 00057, 02875 = 0. 29)Units are expressed after the number as above.

1.  What will the pressure be in atm when a gas at 7 atm is heated from 15 to 30 degrees Celsius, if the volume stays at a constant 5L?
2.  400L of gas is stored at 100 degrees Celsius at a pressure of 709kPa. The gas is moved to a tank that is 20 degrees Celsius cooler and the pressure of the tank is 3000kPa. What is the volume of the gas in L?
3.  A gas is stored in a balloon at a pressure of 760 mm - Hg at 50 degrees Celsius. . The balloon is heated until the temperature is 100 degrees Celsius. What is the pressure in mm-Hg.
4.  A gaseous sample of carbon dioxide occupies a volume of 3.27 L at a temperature of 20 degrees Celsius. If the pressure remains constant, what is the temperature in Kelvin if the volume lowers to 3L?
5.  If a gas is cooled from 290 to 250 degrees kelvin and the volume is kept at a constant volume of 780ml.What was the initial pressure in mm-Hg if the final pressure is 810 mm-hg?
6.  A gas occupies 15 L at a pressure of 80 mm-Hg. What is the volume when the pressure is increased to 525 mm-Hg?
7.  . A gas occupies 15 L at a pressure of 5 atm. What is the volume when the pressure is increased to 10 atm but the temperature remains at 273 degrees kelvin?
8.  The temperature of a 10 L sample of gas is at 500 degrees kelvin and lowers to 300 degrees kelvin, What will the volume of the gas be if the pressure remains at a constant of 150 kPa?
