Heat transfer

Heat Transfer: moving heat from one place to another.

Conductor of heat is able to pass on heat from one thing to another.

Examples of a conductor
1. Like a heater the heat will pass on particles then all that hot air will release
2. A hot shower will transfer heat from the water to the skin

Insulator of heat is something that does not pass on heat

Examples of Insulator

1.  Pink bats hold hot air stoping it from leaving a home or etc
2. Rubber does not pass energy

Convection: heat transfer without contact hot air rises and cold air sinks

why does convection cause flammable stuff to float up? I think I because hot air less dense cold air more dense [heavy] which causes the hot air to float up but eventually, the hot air will turn cold and it will sink to the ground.
