Heat Flashcards
Heat is a force of
energy
What is a Joule
Unit of heat
When do Solid, liquids and gasses expand
When heated
When do Solid liquids and gasses contract
When cooled
What is a Bimetallic strip
The different metals will expand and contract at different rates due to their molecular properties
What is a Conduction
Heat travels from particle to particle along a substance
What is a Convection
Heat travels through the fluid when the particles move and carry the heat
What is Radiation
Heat travels through a hot object without a medium does not need a solid, liquid or gas to go through will flow through a vacuum
What is a Conductor
Something which allows energy to flow through it E.G metal
What is an Insulator
A substance which dosnt allow energy to pass through. E.G WOOD OR PLASTIC
What form of energy and is measured in joules (J)
Heat
Do Materials expand when heated and contract when cooled.
Yes
