If you keep ice at `0^(@)C` and water at `0^(@)C` in either of your hands, in which hand you will feel more chillness? Why?

If you keep lee at 0^(C) C and water at 0^(@)C in either of your hands, in which hand you will feel more chillness? Why?

Hold a sheet paper in one hand and a book in other hand. Which hand feels heaviness?Why?

Ice is less dense than water at 0^(@)C . Justify this statement.

One end of a steel rod (K=46Js^(-1)m^(-1)C^(-1)) of length 1.0m is kept in ice at 0^(@)C and the other end is kept in boiling water at 100^(@)C . The area of cross section of the rod is 0.04cm^(2) . Assuming no heat loss to the atmosphere, find the mass of the ice melting per second. Latent heat of fusion of ice =3.36xx10^(5)Jkg^(-1) .

Can you guess why there are sweat glands on the palm of our hands and the soles of our feet ?
