Flashcards in Energy Quiz 2+3 Deck (19):
0

What is thermal energy

KE
PARTICLE MOTION

1

Chemical

PE stored in bonds

2

Radiant

Electromagnetic energy of EM waves

3

Nuclear

PE KE
STORED IF BROKEN ENERGY RELEASED

4

Electrical

KE and PE
Potential to turn back on

5

Mechanical

KE and PE
K moving
P freeze stay in position

6

Describe how the amount of kinetic and potential energy change in a moving object

Potential energy height mass gravity
Kinetic mass and speed
Potential energy falls turns into kinetic

7

Potential energy

PE= MGH

8

K energy

1/2MV

9

What is heat

Total amount of kinetic energy

Total hotness
Mass + avg speed of particles

10

Heat formula

H = MT

Q = MC

11

2nd law of thermodynamics

Heat spontaneously flows from hot to cold
Energy isn't destroyed, escapes

12

2 substances with different temp

Eventually be the same
Energy from particle motion transferred

13

Greater temp difference

Greater amount of energy transfer

14

Collision

Fast collide with slow
Slow speed up
Fast slow down

15

What happens when a molecule goes faster and slows down

Expands
Contracts when slow

16

Temp

Motion of particles
Faster, higher temp
Slower, lower temp
Substance fast/slow

17

Temp is the measure of

Avg KE
Not total heat energy

18

Heat VS temp

Heat total KE
Temp avg KE
