Particles In Motion Flashcards
0
Q
Thermal expansion
A
Increase in vol=
Increase in temp
Increase in particle collision
Particles push each other apart
1
Q
Temp
A
Is the meas of avg KE in particles of a mtrl
2
Q
Thermal energy
A
moves from warm to cool materials
3
Q
Vaporization
A
Water vapes at 100C
Kinetic energy remains same
Liq vape in two ways:
Boiling is vape that happens within a liquid
Evaporation is vape that occurs on the surface of a liquid
4
Q
Condensation
A
Removing thermal energy from a liq
5
Q
Sublimation
A
When a solid turns to has without passing through liquid stage
6
Q
Deposition
A
Change from gas to solid bypassing liquid
7
Q
Thermal conductors
A
Contain electrons that move freely. This movement allows the thermal energy to travel from end to end without loosing energy
