Answer

(i) The process of splitting of a heavy nucleus into two lighter nuclei of nearly same mass, when bombarded with slow neutrons, is called nuclear fission.

(ii) $_{92}^{235} U$ + ${0}^{1}\text{n}$ ⟶ $_{56}^{144} Ba$ + ${36}^{89}\text{Kr}$ + 3 $_{0}^{1}\text{n}$ + Energy

104 g of water at 30°C is taken in a calorimeter made of copper of mass 42 g. When a certain mass of ice at 0°C is added to it, the final steady temperature of the mixture after the ice has melted, was found to be 10°C. Find the mass of ice added.
[Specific heat capacity of water = 4.2 J g^-1 °C^-1; Specific latent heat of fusion of ice = 336 J g^-1; Specific heat capacity of copper = 0.4 J g^-1 °C^-1 ]
