Question 10

Thermal energy

Answer 10

Is meaured in joules

Question 11

Conduction

Answer 11

Transfer of thermal energy through the vibration of particles

Question 12

Good thermal conductors

Answer 12

Metal becuase it comtains electrons which are free to move

Question 13

Insulators

Answer 13

Material that doesnt allow heat electricity or sound tp pass through or come out of

Question 14

Poor conductors

Answer 14

Gasses and liquids (their particles are spreadout and do not colliade often

Question 15

Convection

Answer 15

Is the transfer of thermal engergy in a liquid of gas

Question 16

Convection current

Answer 16

When more dense particles move to the bottom, nearest to the heat source, which creates a constant flow of partcicles
