Equal masses of ice `(at 0^@C)` and water are in contact. Find the temperature of water needed to just melt the complete ice.

m' mass of ice at 0^(@)C is put in same mass of water. Find the temperature of water needed just to melt the ice completely.

Equal masses of ice at 0^(@) C and water at 100^(@) C are mixed. The resultant temperature is

Equal masses of ice and water with temperature equally below and abovve the melting point of ice respectively are mixed with each other. At equilibrium 40% of the ice melted. The initial temperature of water was

15 g ice at 0^@C is mixed with 10 g water at 40^@C . Find the temperature of mixture. Also, find mass of water and ice in the mixture.

15 g ice at 0^@C is mixed with 10 g water at 40^@C . Find the temperature of mixture. Also, find mass of water and ice in the mixture.

When ice melts into water entropy

Ice is formed on the top surface of a lake. Temperature of air above ice is -15^(@)C , (i) What is the temperature of the water layer just below ice? (ii) Find the maximum possible temperature at the bottom of the lake.

Temperature of water at the surface of lake is – 20°C. Then temperature of water just below the lower surface of ice layer is
