Gas Laws Quiz #1

8 Questions  I  By Robert Stine
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.  A gas occupies 10 L at an unknown pressure. What is the initial pressure, if the final volume is 5L and the pressure is 5atm?
2.  A gas has a pressure of 630 mm-Hg at 296 degrees kelvin. At standard pressure what is the temperature of this gas in K?
3.  At 200 degrees Celsius a gas has a volume of 380ml. What will the volume be in mL at 300 degrees Celsius ( pressure remains constant).
4.  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?
5.  A gas is cooled from 350 to 300  degrees kelvin, with a constant volume of 5L. What would the final pressure of the gas be in mm-Hg if the initial pressure measures at 850 mm-hg?
6.  A gas has a volume of 10L at - 100 degrees Celsius and .94atm. What would the volume of the gas be in L if the temperature increased to 100 degrees Celsius and the pressure to 1 atm?
7.  What is the temperature in Kelvin when a gas that occupies 1L at 15 degrees Celsius is compressed to .5L?
8.  A sample of gas occupies 15L at 300 degrees kelvin and 350kPa. What is the pressure in kPa if the temperature rises to 500 degrees kelvin and the volume to 30L?
