Ideal Gas Law

In order to solve gas law calculations, temperature must be measured in:

• Fahrenheit

• Celsius

• Kelvin

• It doesn't matter 

How many grams of oxygen will occupy a volume of 2.50 L at 1.20 atm and 28C?

• 0.121 g

• 3.88 g

• 8.23 g

• 8.97 g

What will happen to the Volume if it was 5.5 L while the Pressure started at 2.7 atm and increased to 3.6 atm? PV=nRT

• Volume increases

• Volume decreases

What will happen to the pressure of a gas that is compressed to a volume of 5.0 mL when it originally occupied a volume of 50.0 mL under 1.75 atm of pressure? PV=nRT

• Pressure increases

• Pressure decreases

A sample of gas has a volume of 852 mL at 25°C. What will happen to the temperature if the volume increases to 945 mL? PV=nRT

• Temperature increases

• Temperature decreases

Determine the Celsius temperature of 2.49 moles of gas contained in a 1.00-L vessel at a pressure of 143 kPa. Solve for T and then change you answer to Celcius

• -266 degrees C

• -622 degrees C

• 622 degrees C 

• 266 degrees C

A balloon with a volume of 5.3 L is taken from an indoor temperature of 24ºC to the outdoors. The volume of the balloon outside is 4.9 L. What happened to the Celsius temperature outside? PV=nRT

• Temperature increase

• Temperature decreases

In order to solve gas law calculations, temperature must be measured in:

• Celsius

• Fahrenheit

• Kelvin

• It doesn't matter

What is the ideal gas law equation?

If the pressure of a gas is doubled while the temperature remains constant, what happens to the volume?

• Volume doubles

• Volume halves

• Volume remains the same

• Volume quadruples
