States of Matter

Front

All of the following are properties of ideal gases except:
Gas molecules do not interact with each other except during collisions,
Collisions between gas molecules are completely elastic,
Volume occupied by molecules is negligible compared to the volume occupied by the gas,
Small amounts of energy are lost during collisions between gas molecules

Back

Small amounts of energy are lost during collisions between gas molecules

Front

The temperature of a gas depends on the average __________ of the particles of the gas.

Back

kinetic energy

Front

What two assumptions from the Kinetic Molecular Theory explain why gas expands? -Gas particles move rapidly in all directions & -Do not have significant attraction to one another

Back

-Gas particles move rapidly in all directions & -Do not have significant attraction to one another

Front

What accounts for the fluidity of gases?

Back

Gas particles have low IMF so they glide past one another.

Front

What accounts for the low density of gases (about 1/1000th the density of the same substance in a liquid or solid state)?

Back

The large distance between the particles in a gaseous state

Front

Why are gases so easy to compress?

Back

Because their particles are so far apart, there is a lot of empty space between them

Front

When a gas is compressed, its volume is _______ ________

Back

greatly decreased

Front

The spontaneous mixing of the particles of two substances caused by their random motion

Back

Diffusion

Front

A process by which gas particles pass through a tiny opening

Back

Effusion

Front

What is the relationship of gas velocity and effusion rate?

Back

As the velocity increases, the effusion rate increases.
