... A cube of copper of mass mc=75 g is placed in an oven at a temperature of T0=3120C until it comes to thermal equilibrium. The cube is then dropped quickly into an insulated beaker(烧杯) containing a quantity of water of mass mw=220 g. The heat capacity of the beaker alone is Cb=190 J/K. Initially the ...

... temperature. Since we can only measure temperature we can rewrite: q C.dT C (T2 T1 ) Generally C does not vary much with temperature except near phase transition. T2 and T1 are the final and initial temperatures. So if system cools then the sign of q is negative since it looses heat to surro ...
