A metal rod AB of length 10x has its one end A in ice at 0^@C , and the other end B in water at 100^@C . If a point P one the rod is maintained at 400^@C , then it is found that equal amounts of water and ice evaporate and melt per unit time. The latent heat of evaporation of water is 540cal//g and latent heat of melting of ice is 80cal//g . If the point P is at a distance of lambdax from the ice end A, find the value lambda .

An ice ball of radius a and mass m is placed at 0^@C inside a thick hollow sphere of inner and outer radii a and b whose thermal conductivity varies as k=alpha/r^2 , where alpha is a positive constant and r is the distance from centre. The temperature of surrounding is theta_0 and latent heat of fusion for ice is L_f . Then , time required to completely melt the ice ball is (Neglect the contraction in volume when ice melts into water and any change in thermal resistance due to melting of ice of the system.)

A thin copper rod of uniform cross section A square metres and of length L metres has a spherical metal sphere of radius r metre at tis one end symmetrically attached to the copper rod. The thermal conductivity of copper is K and the emissivity of the spherical surface of the sphere is epsi .The free end of the copper rod is maintained at the temperature T kelving by supplying thermal energy from a P watt source. Steady state conditions are allowed ot be established while the rod is properly insulated aginst heat loss from its lateral surface. Surroundings are at 0^@C Stefan's constant =sigmaW//m^(2) K^(4) . The net power that will be radiated out, P_S from the sphere after steady state condition are reached is

The bond dissociation energy depends upon the nature of the bond and nature of the molecule. If any molecule more than 1 bonds of similar nature are present then the bond energy reported is the average bond energy. Heat evolved when 0.75 mol of molten aluminium at its melting point of 658^(@)C is solidified and cooled to 25^(@)C . The enthalpy of fusion of aluminium is 76.8 "cal" g^(-1) and C_(P)= 5.8 "cal" mol^(-1) ""^(0)C
