Answer 3

A material that doesn’t let heat pass through it

Question 4

Convection

Answer 4

Heat transfer in a fluids

Question 5

Radiation

Answer 5

Heat transfer in a vacuum. Another name for heat and tracked in infrared waves

Question 6

Convection current

Answer 6

A current created by heat causing changed in the density of a fluid

Question 7

Expansion

Answer 7

When particles are heated they expand and vibrate faster

Question 8

Contraction

Answer 8

When particles are cooled they vibrate slower and contract

Question 9

Melting point

Answer 9

The temperature when a solid is melted to a liquid

Question 10

Freezing point

Answer 10

The temperature where a liquid freezes to a solid (same temp as melting point)

Question 11

Boiling point of water

Answer 11

100 degrees

Question 12

Freezing point of water

Answer 12

0 degrees

Question 13

Less dense

Answer 13

More gaps and particles further apart

Question 14

Heat

Answer 14

Type of energy and is measured in joules

Question 15

Temperature

Answer 15

How hot or cold something is and measured in degrees Celsius

Question 16

How a thermometer works

Answer 16

Particles are liquids
As the material gets hotter it gains more energy and particles move more
Mercury in thermometer gets heated and moves up

Question 17

Vacuum

Answer 17

A place with no particle

Question 18

Metals are good conductors

Answer 18

Metals have free electrons which collide with other atoms and pass on heat energy

Question 19

Shiny objects in radiation

Answer 19

They absorb less heat but reflect it so cools down slower

Question 20

Black objects

Answer 20

Absorb more energy by emit more energy so cools down quicker
