#### Solution Preview

To melt the block and raise the temp of water to 50 C we need to supply latent heat to melt the block and then to raise it from a temperature of 0 degrees Celsius to 50 degrees celsius

We assume that the block of ice is at a temperature of 0 degrees Celsius

Let the mass of the block be m Kg

The specific latent heat of fusion of ice at 0 ÂºC, is 334 kJ.kg-1. ...

#### Solution Summary

Calculates the height from which a block of ice is dropped so that the energy obtained would be enough to melt the block and raise the temp of the water to 50 C.
