A calorimeter of water equivalent 50 g contains 100 g water at `30^(@)C`, in each of the situations, select the option(s) that indicate the correct final temperature

450 g water at 40^(@)C was kept in a calorimeter of water equivalent 50 g 25 g ice at 0^(@)C is added and simultaneously 5 g steam at 100^(@)C was passed to the calorimeter. The final temperature of the calorimeter. Will be (L_(ice)=80 cal // g.L_(steam) =540cal//g)

A calorimeter of water equivalent 15g contains 165g of water at 25^(@)C . Steam at 100^(@)C is passed through the water for some time .The temperature is increased to 30^(@)C and the mass of the calorimeter and its contents is increased by 1.5g Calculate the specific latent heat of vaporization of water. Specific head capacity of water is 1(cal)/g^(@)C .

1 g of steam at 100^(@)C is passed into a calorimeter of water equivalent 10g containing water of mass 90 g. Find the resultant temperature of the mixture if the initial temperature of water is 27^(@)C .

50 g of an alloy containing 80% copper and 20% silver is heated up to t_(1)=80^(@)C and then dropped in a calorimeter of water equivalent W = 10 g containing m = 90 g of water at t_(2)=20^(@)C . What will be the final temerature of the mixture ? Specific heat capacity of copper and silver are s_(c)=0.09" cal.g"^(-1).^(@)C^(-1) and s_(s)="0.15 cal.g"^(-1).^(@)C^(-1) respectively.
