Return to 6 KS5 Further Mechanics and Thermal

19 Thermal Physics

This is a page for resource for the Thermal Physics section of the book. With this unit remember a couple of common issues. Don’t get confused and make simple calculating errors such as including the temperature in a latent heat calculation. As always, practice is the key. Converting kelvin incorrectly is a common source of error.

Liquid Mercury Freezing with Dry Ice Sublimation

This is a really cool practical to show how a solid can take energy from a liquid and make it into a solid.

Freezing point of mercury is -38.83 °C

Freezing point ...
of CO2 is −78.5 °C

So clearly the internal energy of the mercury was reduced to a lower amount and the temperature decreased!
