Front 10

What is the main difference between electrical and fored-air heating systems?

Back 10

electrical systems have no furnaces and no fuel is burned. forced air systems use fuel-burning furnaces

Front 11

Back 11

conductor

Front 12

What changes thermal energy into mechanical energy?

Back 12

heat engine

Front 13

what are usually the best conductors of heat

Back 13

metals

Front 14

acting solar heating

Back 14

collecting the sun's energy with solar panels, heating water with that energy and storing the heated water to use the energy later.

Front 15

in solar heating systems, radiant energy from the sun is converted into?

Back 15

thermal energy

Front 16

what are important considerations when selecting insulation for a house?

Back 16

R-value
location
climate

Front 17

how does conduction differ from convection?

Back 17

in conduction, particles remain in place, in convection, fluid particles move from place to place

Front 18

what is the most important way thermal energy is trasferred in fluids?

Back 18

convection

Front 19

What does no require the presence of particles of matter?

Back 19

radiation

Front 20

insulator

Back 20

a device that does not allow heat or electrons to move through it easily

Front 21

conduction

Back 21

The transfer of energy through matter in which energy moves from particle to particle, easier in solids

Front 22

combustion

Back 22

rapid burning

Front 23

In order for radiant energy to change to thermal energy, it must be?

Back 23

absorbed

Front 24

How is energy transferred?

Back 24

particles moving at different speeds bump into each other

Front 25

convection

Back 25

transfer of energy by bulk movement of matter in which particles move from place to place in a fluid, carrying the energy with them.

Front 26

fluid

Back 26

any liquid that flows liquids and gasses are fluid

Front 27
