When particles are given heat energy they move faster, this because they gain kinetic (movement) energy. |
|
What type of energy do particles gain when they are heated? |
|
|
| W |
A change of state from solid to liquid, liquid to gas or solid to gas requires an increase of the internal energy of the material. |
|
How does the internal energy of a material change as state changes? |

| D |
Add energy arrows to diagram from previous lesson. |

DESIRABLE:
Latent heat experiment such as:
Practical 26 - Classic Chemistry Practicals
SHARED AREA\KS3\Other Resources\ClassicExp\Kev21-30.doc
or

Ideally heating though. I like the idea measuring the water bath and the stearic acid.
Good opportunity for data loggers. |

An increase of the internal energy of the material does not always result in a increase in temperature. Some energy is used in order to change state. |
|
Why does the temperature of water not increase during melting and evaporation? |
|
|
| W |
Internal energy is the sum of kinetic energy and the potential energy stored in the stretch 'attraction' between the particles. |
