Question

A copper sphere of mass 200 g is heated to raise its temperature to 100°C
and is released in water of mass 150 g and temperature 20°C, in a copper
calorimeter. If the mass of the calorimeter is 50 g, then maximum
temperature of water will be
(specific heat of copper=0.10 cal/g°C: specific heat of calorimeter = 1 calg°C)
23.2°C
27.2°C
3) 50°C
D 20°C​
