Ideal and Combined Gas Laws

Which gas law allows us to look at how three different properties of a gas change simultaneously?

• Combined Gas Law

• Charles's Law

• Ideal Gas Law

• Boyle's Law

Which gas law allows us to solve for one unknown property of a gas, without changing any properties of the gas?

• Avogadro's Law

• Charles's Law

• Ideal Gas Law

• Combined Gas Law

What is the pressure of a car tire that had an initial pressure of 1.8 atm but was heated from 38°C to 123°C?

• 0.9 atm

• 2.3 atm

• 1.6 atm

• 3.4 atm

When a cold tire is inflated to a certain pressure and then is warmed up due to friction with the road, the pressure increases. This happens because the

• air molecules hit the walls of the tire less frequently

• rubber in the tires reacts with oxygen in the atmosphere

• air molecules speed up and collide with the tire walls more often

• air molecules diffuse rapidly through the walls of the tire.

You have a gas that has a pressure of 2 ATM and a volume of 10L.  What would be the new volume if the pressure was changed to 1 ATM?

• 5 L

• 20 L

• It would stay at 10L

• 1 L

Consider a sample of oxygen gas at 27° C with a volume of 9.55L at a pressure if 2.97 atm. The pressure is changed to 8.25 atm and the gas is heated to 125° C. What’s the new volume?

• 4.56 L

• 4.67 L

• 15.9 L

• 16 L

If I have 5.6 liters of gas in a piston at a pressure of 1.5 atm and compress the gas until its volume is 4.8 L, what will the new pressure inside the piston be?

• 75 atm

• 1.8 atm

• 1.3 atm

• 1.29 atm

What pressure, in atm, is exerted by 2.50 L of gas containing 1.35 mol at 320 K?
PV=nRT

• 14.19 atm

• 16.53 atm

• 18.42 atm

• 22.54 atm

What is the pressure exerted by 5.00 moles of nitrogen gas contained in a 30.0 Liter container at 25.0 °C?

• 3670 atm

• 0.245 atm
