Light snow solar shell

The amount of heat required to raise or lower 1kg is only related to the kind and state of the substance.

2.243ml=250g, so

Heat absorbed by milk when heated: q absorption = c1m1(t-t0) =18750j.

The heat released when hot water is cooled from 60℃ to 42℃ is q =C2M2(T0`-T).

Q suction =Q discharge, so M2=Q discharge/C2 (t0`-t) = 0.248kg.
