Gas Laws Quiz #1

8 Questions  I  By Robert Stine
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 is compress 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. Include a space in between the number and the unit. 2. 4 atm not 2. 4atm. You can miss 1 question and earn the Certificate of Achievement.

1.  A sample gas occupies 0.5 liters at 30 degrees Celsius and 2000 mm - Hg. What is the temperature in Kelvin at which the gas will occupy 1 liter at 2280 mm-Hg
2.  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?
3.  A 700 ml sample of helium is warmed from 60 to 80 degrees Celsius. What is the new volume in mL of the sample if the pressure remains as a constant, of 5 atm.
4.  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?
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 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.
7.  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?
8.  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?
