Question 1

Conduction

Answer 1

Thermal energy through matter by direct contact of particles

T.E matter direct contact

Ex. Touch Snow

Question 2

Convection

Answer 2

Thermal energy fluid by the movements of warmer objects

T.E. fluid in warmer objects

Ex. Warmer particles expand; cooler particles close

Question 3

Radiation

Answer 3

Transfer of energy by electromagnetic waves.

Transferring of electromagnetic waves

Ex. Light, microwave

Question 4

Thermal Insulator

Answer 4

Material which thermal energy moves slowly

Thermal energy moves slower in it

Ex. Wood, Gases, Air

Question 5

Thermal Conductor

Answer 5

The ability of a material to allow the flow of heat from it’s warmer surface through the material of its cooler service.

A materials ability to flow it’s heat from the surface that is warm through the cooler surface material

Ex. Car sitting in the sun

Question 6

How do convection currents work?

Answer 6

Created by temperature differences and is the movement of groups of molecules

Question 7

What happens to Sun’s radiation as it hits Earth?

Answer 7

It is either reflected, absorbed or transmitted

Question 8

How does radiation occur? Move through solids? Liquids? Gasses?

Answer 8

It depends on the color and type of material. It makes liquids evaporate. It makes solid very hot. And it makes gases warm
