cooling curve
Cooling curve Two temperature sensors can collect some interesting information about cooling during a change of state. In this experiment the temperature of a water bath increases as a substance cools. But the unusual...

latent heat – salty ice
When it is icy they put salt onto the roads to melt the ice. What the salt does is to depress, or reduce, the freezing point of water. The result is that the ice...
freezing a bun or bread roll
We scientists do the strangest of things. We wanted to see the temperature changes when you freeze and thaw things. So we took a ‘bun’ (a bread roll), placed temperature sensors in and around...
heating ice
You would think that when you heat up ice that it gets warmer bit by bit. And maybe that the more you heat it the hotter it gets. Well it’s not like that. We...
