Question 7

What is the Compression of Gases?

Answer 7

High.

Question 8

Answer 10

Moderate.

Question 11

What is the Thermal expansion of Liquids?

Answer 11

Low.

Question 12

What is the Thermal expansion of Solids?

Answer 12

Very low.

Question 13

What is the Kinetic Theory of Matter?

Answer 13

The Kinetic Theory of Matter describes the properties of matter in terms of particles in motion. KE=1/2*m(v^2).

Question 14

How does Temperature affect the movement of particles?

Answer 14

The colder something becomes, the slower the particles move. At absolute zero, they (the particles) don’t move at all.

Question 15

What are Elastic Particle Collisions?

Answer 15

The particles collide with each other and transfer energy without incurring an energy loss - these are elastic collisions.

Question 16

What is the Formula for Graham’s Law of Diffusion?

Answer 16

The rate of diffusion equals one divided by the square root of the molar mass.
