Question 13

The pressure of a gas in a container is 76 mm Hg. This is = to ….. atm.

Answer 13

76 mmHg (1 atm/760 mmHG) = 0.1 atm

Question 14

Answer 14

have motion that is constant, random, and rapid.

Question 15

How should atmospheric pressure change as you climb a mountain?

Answer 15

Pressure decreases as you climb the mountains.

Question 16

What is Absolute Zero?

Answer 16

Absolute zero is the lowest temperature theoretically possible when particle motion stops completely.
