• 7.18 L

• 7.81 L

• 4.63 L

• 4.36 L

Determine the Kelvin temperature required for 0.0470 mol of gas to fill a balloon to 1.20 L under .998 atm pressure.

• 0 K

• 107 K

• 207 K

• 307 K

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

• 14.19 atm

• 16.53 atm

• 18.42 atm

• 22.54 atm

Which of the following would increase the pressure on a system?

• Increase the Temperature

• Pump in more gas

• Decrease the volume

• All of these

Rates of effusion of different gases are proportional to their...

• polarity.

• particle charge.

• particle velocities.

• compressibility.

The pressure exerted by a gas does not depend on

• temperature.

• volume.

• number of moles present.

• the identity of the gas.

Pressure is caused by:

• Gas molecules colliding with surfaces

• Gas molecules reacting with each other

• Gas molecules colliding with each other

• Gravity
