The opposite faces of a cubical block of iron of cross section 4cm2 are kept in contact with steam and melting ice. Calculate the quantity of ice melted at the end of 10min. Given k for iron=0.2cal/s cm C degree.

Step 1

The heat transfer equation is given by

Step 2

The heat flows for 10min, i.e. heat absorbed by ice .

Step 3

This heat flow is equal to the latent heat of fusion times the mass of melted ice.
