Lab: latent heat of vaporisation.

Aim: <Tab/>To investigate the Latent Heat of Vaporisation of water. <Tab/>Independent Variables: voltage / energy <Tab/>Dependent Variables: temperature Controlled Variables: amount of water, voltage and current We won't consider uncertainties here since it is a planning lab. Hypotheses: The water will heat up at a quicker rate if a lot of energy is added instead of a small amount of energy. …showed first 75 words of 497 total…

As we want to find and we know that and the gradient of the graph represents we then know that which is the same as we take the gradient out of the graph and then re-arrange the equation so that we get : Having the gradient and having V and I which are constant we can finally find the Latent Heat of Vaporization by re-arranging the equation and solve for as shown in the graph.
