Thermal Physics

Question 1

conduction

Answer 1

transfer of heat energy through the transfer of the kinetic energy between particles

Question 2

can convection occur in solids

Answer 2

no

Question 3

convection current

Answer 3

transfer of thermal energy from one part of the liquid to another

Question 4

conduction

Answer 4

transfer of thermal energy through the transfer of kinetic energy between particles

Question 5

best conductors

Answer 5

metals –> free electrons – >move faster through lattice

solids –> particles bound more closely

Question 6

how can you increase conduction

Answer 6

increase temperature gradient & surface area of particles in contact with surrounding matter

decrease distance between particles

Question 7

is conduction or convection faster

Answer 7

convection

Question 8

how can energy be transferred through vacuum

Answer 8

by radiation

Question 9

good absorbers of thermal radiation emission

Answer 9

matt objects

Question 10

good reflectors of thermal radiation emission

Answer 10

shiny objects

Question 11

how fast is radiation

Answer 11

speed of light (EM waves)

Question 12

what kind of objects emit radiation

Answer 12

all objects above 1K
