Q

What happens when gases mix together and why

A

They form a solution bc they don’t exhibit intermolecular forces bc too far apart

Q

Explain kinetic molecular theory

A

Gases consist of molecules that are in continuous random motion
Volume of molecules is negligible compared to the volume of the gas container
Molecular attractions and repulsions are negligible
Molecules undergo elastic collisions
The average kinetic energy is proportional to the absolute temperature (kelvin)

13
Q

How do gases deviate from their behavior

A

Molecules become more tightly packed and their volume is no longer negligible
Attractive and repulsive forces start to take hold

Q

How do the sizes of gases come into play

A

Small simple gases will behave ideally longer that that of larger gases
