What is latent heat of fusion?

Define latent heat of fusion.

A copper block of mass 2.5 kg is heated in a furnace to a temperature of 500^2C and then placed on a large ice block. What is the maximum amount of ice that can melt? (Specific heat of copper = 0.39 J g-^1K ^-1 , heat of fusion of water = 335 J g^-1)

When 0.2 kg of ice at 0°C is mixed with 0.40 kg water at 50°C,the resulting temperature is 7°C,Find latent heat of fusion of ice,(Give s-w=4186 Jkg^-1 K^-1)

When 0.15 kg of ice at 0^@C mixed with 0.30 kg of water at 50^@C in a container, the resutling temperature is 6.7^@C . Calculate the latent heat of fusion of ice. Given S_(water) = 4186J kg^-1 K^-1 .
