Concept 3 Unit 6

Question 1

Temperature

Answer 1

Measure of the average kinetic energy of particles

Question 2

Plasma

Answer 2

Matter composed of positively and negatively charged particles with EXTREMELY high kinetic energy

Question 3

Bose-Einstein condensates

Answer 3

Atoms are super cooled to such low temperature that they form a super atom

Question 4

Heat of fusion

Answer 4

The amount of energy needed to turn a solid into a liquid at its melting point

Question 5

Heat of vaporization

Answer 5

The amount of energy needed to turn a liquid into a gas at its boiling point

Question 6

Vaporization

Answer 6

The phase transition from liquid to gas

Question 7

Evaporation

Answer 7

Caused by pressure change occurs only at the surface of a liquid

Question 8

Boiling

Answer 8

Caused by a temperature change occurs throughout the liquid

Question 9

3 matter keys

Answer 9

1- All matter is made of small particles
2- The particles are constantly moving
3- The motion of the particles cause them to collide

Question 10

Solid- it’s volumes shape and particule movement

Answer 10

Solid is a fixed volume
Fixed shape
And the particles are ridgid/held tightly together barely moving(vibrating)

Question 11

Liquid-volume shape and particle movement

Answer 11

Liquid is a fixed volume
Not a fixed shape
Particles have more kinetic energy then solids(slide past eachother)

Question 12

Gas- volume shape movement

Answer 12

Gas does not have a-fixed volume
Has no shape
And particles have high kinetic energy ( bouncing)

Question 13

State change is chemical or physical and why

Answer 13

Physical because it doesn’t change its identity
