Answer 9

The ability to move something somewhere

Question 10

Potential energy

Answer 10

GPE

Question 11

Heat vs temperature

Answer 11

Heat - type of KE that flows from hot to cold , causes change in temp , and is in Joules
Temp - measurement of avg motion of molecules in a substance , affected by transfer of heat, and measured in F and C.

Question 12

How does a thermometer work

Answer 12

Outside - person -> liquid in therm , absorbs heat E , molecules speed up and expand, move apart which causes liquid to rise
Inide-
Liquid in therm -> cold water
Releases heat E , molecules slow down contract or move closer cause the liquid in the therm fall.
