Insulators wuch as wood, polystyrene and wool keep the heat in because the have trapped air inside them. I guess you would say that conductors (such as metal)keep the heat out because heat flows through them. Once they are warmed up and taken away from the heat, they start releasing the heat inside.
Heat is useful as It IS our main heat source keeps us warm and help us in our daily lifes. Solar Panels are used to trap Heat
the aluminum insulates the heat and keeps it in there so no heat to get out if so only a little will
It keeps heat from outside the refrigerator from getting into the refrigerator.
An insulator is an object that does not conduct (allow something to flow through it). It is used typically in heat or electricity applications. For example, insulation in a house, keeps heat from escaping outside.
styrofoam, but warning fammable and unsafe for the environment!
Under Armour Heat Gear keeps you cool, while Cold Gear keeps you warm.
it is the heat
insulator is a object that is not a good conductorSo it keeps the heat in.
it keeps out water and keeps in heat
styrofoam
a lot
The skin keeps it in.
spell hear
Because it traps the heat that comes from your body from escaping, so you have more heat so it keeps you warm.
a good insulator of heat keeps the heat in, so you stay warm
Source of heat energy that keeps the surface of the Earth warm enough support LIFE
Styrofoam cups and caps. It keeps the heat in.
