What is meant by saying that the latent heat of fusion of ice is `3.34 xx 10^(5)J//kg` ?

What is meant by saying that the latent heat of vaporisation of water is 22.5 xx 10^(5) J//kg ?

One end of a steel rod of length 1 m and area of cross section 4 xx 10^(-6)m^(2) is put in boiling water and the other end is kept in an ice bath at 0^(@)C. If thermal conductivity of steel is 46 W//m^(@)C, find the amount of ice melting per second if heat flow only by conduction. Given that the latent heat of fusion of ice is 3.36 xx 10^(5)J//kg.

The specific latent heat of fusion of ice is …………….

When 2 kg blocmk of copper at 100^(@)C is put in an ice container with 0.75 kf og ice at 0^(@)C , find the equilibrium temperature and final composition of the mixture. Given that specific heat of copper is 378 J/kg K and that of water is 4200J/kg K and the latent heat of fusion of ic eis 3.36xx10^(5) J/kg

Find the final temperature and composition of the mixtue of 1 kg of ice at 0^(@)C and 1.5 kg of water at 45^(@)C . Given that specific heat of water is 4200 J/kg and latent heat of fusion of ice is 3.36xx10^(5)J//kg

How should 1 kg of water at 50^(@)C be divided in two parts such that if one part is turned into ice at 0^(@)C . It would release sufficient amount of heat to vapourize the other part. Given that latent heat of fusion of ice is 3.36xx10^(5) J//Kg . Latent heat of vapurization of water is 22.5xx10^(5) J//kg and specific heat of water is 4200 J//kg K .
