    Hi,

    We have done a practical to investigate Charles' law and extrapolate to find absolute zero. There are a couple of questions on the practical sheet that I don't understand. I'd be really grateful if someone could explain.

    Thanks

    For the first, I'm assuming the graph axes are T and V and the relationship is shown as a line, where k is the gradient (or 1/k, depending on whether T is the x or y axis). So what happens when the gradient of the line (k) changes?

    Second question - if the length is overestimated, what is the volume? If the volume is overestimated, how does that affect your line?
