Question

· A copper calorimeter of mass 100 g and
temperature 30°C contains water of mass 200 g
and temperature 30°C. If a piece of ice of mass
40 g and temperature 0°C is added to it, what
will be the maximum temperature of the
mixture? [c (copper) = 0.1 cal/g. °C, c (water)
= 1 cal/g.°C, L= 80 cal/g] ​

Answer 1

Explanation:

200 g = 30 ° c 40 g = 0 ° c copper = 0.1
