What are the three states of matter?
Solid, Liquids & Gases
1 of 13
Name the three ways energy is transferred.
Infrared radiation (IR), Conduction & Convection
2 of 13
What absorbs IR better Dark, matt or Light, shiny surfaces?
Dark, matt surfaces
3 of 13
What is the main form of heat transfer in solids?
Conduction
4 of 13
What is the main form of heat transfer in Liquids & Gases?
Convection
5 of 13
What can Infrared radiation be emitted by?
Solids, Liquids and Gases
6 of 13
Conduction and convection involve the transfer of energy by what?
Particles
7 of 13
What happens during conduction?
The heat particles vibrate and pass their extra kinetic energy to their neighboring particles
8 of 13
What is a good conductor? Why
Metals. They have free electrons
9 of 13
What happens during convection?
The more energetic particles move from the hotter region to the cooler region - taking their heat energy with them.
10 of 13
What happens in terms of states of matter & particles during condensation
A gas cools and the particles slow down and lose kinetic energy. If it gets cold enough the particles condense. Becoming a LIQUID
11 of 13
What happens in terms particles during evaporation?
It is when particles escape from a liquid.
12 of 13
What are the rules for evaporation?
The particles have to be travelling in the right direction and fast enough.
