In households, a great amount of energy is used to heat up water
- for showers, for washing clothes, for cooking. Exactly how much
is necessary for each degree that each mililitre of water is warmed
up? How are amount of heat, heat capacity and change in temperature
related?
Heat 200 ml of water with an electric heating coil. Measure the
increase in temperature in dependence
on time. Determine the electric power of the heating coil and so
the amount of heat taken up per degree
increase in temperature.
