Water is boiled in a container having a bottom of surface area `25cm^(2)` , thickness `1.0mm and thermal conductivity `50Wm^(-1)`^(@)C^(-1)` , 100g of water is converted into steam per minute in the steady state after the boiling starts.Assuming that no heat is lost to the atmosphere, calculate the temperature of the lower surface of the bottom. Latent heat of vaporrization of water `=2.26xx10^(6)Jkg^(-1)` .

Caclulate the change in entropy of a 1000 kg of water converted into steam. Latent heat of steam =2.268xx10^(6)Jkg^(-1)

A falt-bottom kettle placed on a stove is being used to boil water. The area of the bottom is 270cm^(2) the thickness is 0.3 cm and the thermal conductivity of the material is 0.5 "cal"//s cm^(@)C . If the amount of steam being produced in the kettle is at the rate of 10 g per minute calculate the difference of temperature between the inner and outer surfaces of the bottom. The latent heat of steam is 540 "cal"//gm .

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) .
