Matter And Energy

Question 0

Solid

Answer 0

Definite shape and volume. Particles are rigid with very little movement

Question 1

All matter is made of

Answer 1

Atoms and molecules that act like tiny particles

Question 2

Liquid

Answer 2

Definite volume, NOT definite shape. Particles move more freely

Question 3

Gas

Answer 3

No definite shape or volume. Particles move very fast and spread indefinitely.

Question 4

Temperature, volume, and the number of particles.

Answer 4

Factors that influence gas pressure

Question 5

Energy

Answer 5

The ability to change or move matter

Question 6

To have a phase change,

Answer 6

Energy must be added or taken away

Question 7

Going from solid to liquid to gas and back down. Doe NOT change wha it is made of (composition) or how much you have (mass)

Answer 7

Phase Change

Question 8

Solid to liquid, energy is added (what phase change?)

Answer 8

Melting

Question 9

Liquid to Gas, energy added

Answer 9

Evaporation/boiling

Question 10

Gas to solid- energy taken away

Answer 10

Deposition

Question 11

Solid to Gas, energy added (temperature)

Answer 11

Sublimation

Question 12

Gas to liquid, energy taken away

Answer 12

Condensation

Question 13

Liquid to Solid- energy taken away

Answer 13

Freezing

Question 14

Mass canny be created or destroyed. After a chemical or physical change, mass is ALWAYS the same.

Answer 14

Law of Conservation of Mass

Question 15

Energy cannot be created or destroyed. After a chemical or physical change, energy is always the same.

Answer 15

Law of Conservation of Energy

Question 16

All matter is made of atoms and molecules that act like tiny particles. These tiny particles are always in motion. At the same temp, more massive, or heavier particles, move slower than lighter particles.

Answer 16

Kinetic Theory
