Question 29

The absolute temperature of a gas is _ related to the velocity of its particles.
When the temperature of the gas increases, the velocity of the particles increases as well.

Answer 29

directly

Question 30

The particles carry more energy when heated, and consequently _ and_ a greater volume.

Answer 30

expands and occupy

Question 31

defined as the amount of space that matter occupies

Answer 31

Volume

Question 32

One of the assumptions of the kinetic molecular theory of gases states that ideal gas molecules have very small volume compared with their container.

Hence, ideal gases can be compressed _.

Answer 32

indefinitely

Question 33

Starting with a large volume, gases gradually compress to a smaller volume.

At a certain smaller volume, large molecules will already stop behaving like an ideal gas, but smaller molecules may continue to behave like ideal gas in the same volume.

Question 34

Gases also tend to expand to fill the entire container.
If you move a gaseous substance from a smaller container to a larger container, it will quickly expand to fill the larger container.
