HEAT CONDUCTORS AND HEAT INSULATORS :fire:
Heat conductors are materials that
allow
heat to flow
Graphite (carbon)
Metal
Mercury
Copper
Lead
Aluminium
Iron
pad heats up, it transfers heat to the part of your body that it is in contact with
materials include grains such as wheat, buckwheat or flax seed
hold the heat for a long time
materials include metal, iron, stainless steel
bottom of pan allows heat to flow quickly from the pan to the food
cooks food easily
material used is iron
heat from the iron is conducted to the shirt
making it easy to iron out all those unsightly wrinkles and make the shirt look sharp
Heat insulators are materials that
prevent
heat flow
Fur
Cotton
Glass
Plastic
Wood
Rubber
materials include fiber glass, cellular glass, foamed plastic
works as a protective barrier to reduce heat transfer
limit the heat going inside home
prevent heat from moving from one place to another
materials include plastics, styrofoam, reflective materials
reduce thermal conduction by making thermal energy more difficult to travel
used to keep liquids warm
materials include polystyrene, wool
trapping tiny pockets of warm air close to the skin between fibers
designed to keep us warm
