Real Gases

If the pressure of gases inside a non-rigid tank doubles, what will happen to its volume?

• it will reduce by half

• it will double

• it will be the same as the amount of pressure

• it will triple

Each container with varying volume has 1.0 mole of oxygen gas at 30.0°C. In which container will pressure be the lowest?

• A

• B

• C

• D

What will happen to the gas pressure as the temperature increases, if the amount and volume of the gas are kept constant?

• the gas pressure remains the same

• the gas pressure decreases

• the gas pressure increases

• there is no significant effect

Last summer vacation, the Lapitan family decided to go to La Union for a swimming activity. On their way to La Union, the tire suddenly exploded. What is the probable explanation for the blown out tire during a long summer drive?

• High temperature causes a decrease in volume.

• The amount of the gases inside the tire is increased.

• The mass of the gases inside the tire increases causing a blown up tire

• The volume of gases increases as the temperature increases, causing a

  blown up tire

• equal to 760 mmHg

• lower than 760 mmHg

• higher than 760 mmHg

Which is most likely to happen when a closed vessel filled with gas is shaken for 2 minutes?
