Gas Laws Test Review #JayChem

What describes the motion of a Gas Molecule?

• Molecules are far apart

• Move in constant, random motion

• It will travel in a straight path

• All of the above

If pressure goes down in a container, what happens to volume when the temperature is held constant.

• Increase

• Decrease

If temperature goes down in a container, what happens to volume when the pressure is held constant.

• Increase

• Decrease

If you add gas particles to the container, what happens to the volume when the pressure and temperature is held constant.

• Increase

• Decrease

How would you convert 34^oC to Kelvin?

• K = ^oC + 273

• ^oC = K + 273

• K = ^oC - 273

• ^oC = K + 273

What formula would you use to solve the following: A 0.562 L container of Helium has a pressure of 9.5 atm. What volume would be necessary to decrease the pressure to 2.4 atm?
