Heat Conductors & Insulators
Facts on Heat Conductors & Insulators
- Heat passes through some materials easily and these materials are called thermal conductors.
- Metals usually feel cold to the touch. Metals are good thermal conductors, because heat passes through them quickly.
- Heat does not pass through some material such as plastic, oven glove, thermal underwear, cork board and wood. These materials are called thermal insulators.
- These thermal insulators are good for keeping heat out as well and in. Some examples of good insulators are - a thermos - keeps hot things hot and keeps cold things cold, cooler - deeps the heat out and keeps the inside cool, and a polystyrene cup keeps the heat in and keeps it hot.
- Remember that a good insulator is a poor conductor.
- Heat loves to travel and will travel from a warmer material to a colder material. The heat will only travel from hot things to colder things and never the other way around.
- Some materials allow heat to travel through easily and some don't. If you boil a tea pot on the stove, the pot becomes too hot to touch and whereas the tea pot handle does not get hot.
