What is the atomic mass of a metal whose specific heat capaity `(1)/(9)` cal/`gm^(@)`C and whose percentage by mass in its superoxide is 36%?

A ball of mass 20 g and specific heat capacity 0.1 cal//g –.^(@)C . The water equivalent of ball is

A solid ball of mass 10 kg at 40^(@)C is gently placed in a liquid of mass 20 kg at 20^(@)C and of specific heat capacity 1 cal//gm-^(@)C . When the thermal equilibrium is attained, temperature of the system is 35^(@)C . The specific heat capacity of solid ball is. Neglect heat capacity of the vessel.

5 gm of ice at -10^@C are mixed with 20 gm of water at 39^@C . Will whole of the ice melt? If so, what is the final temperature of the mixture? Specific heat capacity of ice = 0.5 cal gm^-1 "^@C^-1 and latent heat of fusion of ice = 80 cal gm^-1 , specific heat capacity of water = 1cal gm^-1 "^@C^-1 .
