(pressure1) (volume1) = (pressure2) (volume2)

P1V1 = P2V2

QUESTION 12

List 3 properties of gases

1/27/2015

13

ANSWER 12

• Have low densities and are

compressible.

• Mostly empty space.

• Gases fill containers uniformly

and completely.

• Gases diffuse and mix rapidly.

QUESTION 13

Explain Gay-Lussac’s gas Law

ANSWER 13

• Relates gas pressure to temperature.

• The pressure of a gas increases as the

temperature increases.

• If the volume of the gas does not change. The

pressure decreases as the temperature

decreases.
