The graph, we can see that the more time is passing by, the more the temperature is increasing. The equation for the line is y = O,xx + 24,524 0,0136 Cosec is the slope of the line, meaning that that is how much the temperature is increasing per minute.

The difference can be caused by the uncertainties in the measurements. So I would say that we have proved Joule’s law, since the results of the experiment are close to our hypothesis. Processing data We measured the time (in seconds) and the temperature (co). Time is the independent variable, and the temperature is the dependent variable. By looking at
