solids, liquids, and gasses

Question 4

Particles in matter must _____
to transfer thermal energy by conduction.

Answer 4

Collide

Question 5

Answer 6

matter

Question 7

Conduction transfers _____ without transferring the _____

Answer 7

thermal energy
matter

Question 8

Conduction always transfers energy from _____ temperature to a _____ temperature.

Answer 8

high
low

Question 9

The rate at which conduction transfers thermal energy depends on the type of _____

Answer 9

material

Question 10

why is conduction faster in solids and liquids compared to gases.

Answer 10

the atoms are closer together

Question 11

Why are metals the best conductors of thermal energy?

Answer 11

there are some electrons that are not bound to individual atoms so they can move easily throughout the metal causing a rapid transfer of thermal energy

Answer 12

silver (ag)
copper (cu)
aluminum (al)

ex) …

Answer 13

fluid
gas and liquid

Question 14

_____ is the transfer of thermal energy by a fluid due to the differences in the fluid’s densities

Answer 14

convection

Question 16

Most substances _____ as their temperatures increase.

Answer 16

expand

Question 17

When a fluid expands, its _____ increases.

Answer 17

volume

Question 18

Heated fluids become _____ dense causing the atoms to rise carrying _____ up with the matter and lower temperature _____
dense fluids will fall at the same time creating the convection currents

Answer 18

less
energy
more

Question 19

The _____ drive convection currents.
