Test

Question 1

Solid spacing

Answer 1

closest together

no significant space between particles

Question 2

liquid spacing

Answer 2

not as close as a solid but not as far apart as a gas

Question 3

gas spacing

Answer 3

furthest apart, the particles are moving constantly

Question 4

potential for movement (solid, liquid, gas)

Answer 4

solid - least
liquid - middle
gas - most

Question 5

Filling a container (solid, liquid, gas)

Answer 5

solid - keeps shape and volume
liquid - keeps its volume but will form its shape to the container its in
gas - will take shape and volume of container

Question 6

Kinetic Molecule Theory

Answer 6

1. Gases consist of tiny particles
2. Very small compared to distance between them
3. Particles are in random constant motion, colliding with the walls of the container
4. Particles don’t attract of repel each other
