We’ve covered latent heat in class and I have posted the extra notes I gave you today as a pdf file in case you lose them between now and revision time.  When you are reading them, remember that the worked examples on the last 3 pages are credit level work.
Generating Electricity
Someone asked me about the animation I used last week when we were looking at the generation of electricity. The file is a java applet, this means you will need to install java on your computer if you do not have it already. You can view the animation here. If it won’t run for you, try downloading the free java software.
