Thermal Energy Transfer + Infrared Radiation

Question 1

conduction

Answer 1

solid particles vibrate as they gain kinetic energy

Question 2

convection

Answer 2

liquids/ gases diffuse

Question 3

convection current

Answer 3

cycle of warm particles moving up, cooler particles moving down to heat source, less dense near heat source

Question 4

radiation

Answer 4

infrared radiation waves through a vacuum

Question 5

conductor

Answer 5

(metal) with a high rate of thermal energy transfer

Question 6

why are metals good conductors?

Answer 6

their free electrons can flow, transferring energy quickly

Question 7

why does a pure element have better thermal conduction?

Answer 7

all particles are same size = easier for free electrons to flow

Question 8

infrared radiation

Answer 8

part of E.M spectrum, absorbed and emitted by all bodies

Question 9

longest E.M. wave

Answer 9

radio waves

Question 10

shortest E.M.

Answer 10

gamma rays

Question 11

higher temperature

Answer 11

higher radiation emitted

Question 12

constant temperature

Answer 12

equal rate of absorbing and emitting radiation

Question 13

perfect black body

Answer 13

best emitter, no radiation passes through

Question 14

specific heat capacity

Answer 14

amount of energy it takes to raise 1kg of a material by 1 degrees
