QUESTION 10
Name the 3 Gas Laws
1/27/2015
11
ANSWER 10
Boyle’s Law
Gay-Lussac’s Law
Charles Law
QUESTION 11
What is the formula illustrating
Boyles Law?
1/27/2015
12
ANSWER 11
(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
1/27/2015
14
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.

ANSWER 16
•Plasma is made of ionized
particles and can conduct
electricity
•Gases are made of atoms.
QUESTION 17
