Transcript of Changes of state simulations

Changes of state simulations
To know how changes of state happen
To observe simulations based on changes of state
To demonstrate our understanding of the above

If water vapour (gas) is cooled, it changes to water (liquid). This change is called condensing.

If water (liquid) is cooled, it changes to ice (solid). This change is called freezing. Water freezes at 0°C
Solids and liquids
Heat melts a solid and turns it into a liquid. Cooling freezes a liquid into a solid.

Different solids melt at different temperatures, some high, some low. These are called their melting points.
Imagine that you have just discovered 'changes of state'. Write an article convincing the scientific community about it.
Don't do this at home!
Changes of state
If ice (solid) is heated, it changes to water (liquid). This change is called melting.

Water (liquid) can change to water vapour (gas). This is called evaporation.

If water (liquid) is heated until it boils, it changes to water vapour (gas) very quickly. Water boils at 100°C

Melting points
Different solids melt at different temperatures. Ice melts at 0 degrees Celcius (0°C). Chocolate melts at about 35°C. We say that chocolate has a higher melting point than ice.

Metals, like aluminium and iron, also melt when we heat them. They have very high melting points. They have to be very hot to melt.
Temperature is a measure of how hot or cold things are. You need a thermometer to measure temperature.

Temperature is measured in degrees Celsius (°C).

Ice melts at exactly 0°C.

A hot bath is about 40°C

Water boils at exactly 100°C
