Computation of the specific thermal capacity of water

With the last practical course we should compute the specific thermal capacity of water. The specific thermal capacit is in such a way defined. It gives at how much heat energy one necessarily by a kg of a material by a Kelvin to increase, therefore the unit of the specific thermal capacity is 1kj/kg*K. Over the Wärmekapazoität to compute we filled first 400ml water into a cup and amounted to then the Tempertaur measured, these 21 degrees Celsius we the water with a camping digester, as a butane propane mixture in it was. We weighed the camping digester and it were 317,04g heavily. Subsequently, we heated the water up on a Tempertaur von72 degrees Celsius. Afterwards we measured again the weight of the camping digester and were the result, the camping digester are 311,9g heavily.
