Three rods AB,BC and BD of same length l and cross sectional area A are arranged as shown. The end D is immersed in ice whose mass is 440 gm. Heat is being supplied at constant rate of 200 cal /sec from the end A. Find out time (in sec) in which wholeice will melt. (latent heat of fusion of ice is 80 cal/gm) Given k (thermal conductivity) =100 cal/m/sec/ ""^(@)C,A=10cm^(2),l=1 m

What is the meant by the statement, 'Latent heat of fusion of ice is 80cal/gm ?

Three rods AB, BC and BD of same length l and cross section A are arranged as shown. The end D is immersed in ice whose mass is 440 g and is at 0^@C . The end C is maintained at 100^@C . Heat is supplied at constant rate of 200 cal/s. Thermal conductivities of AB, BC and BD are K, 2K and K//2 , respectively Time after which whole ice will melt is ( K=100 cal//m-s^@C A=10cm^2,l=1cm )

What power is gained by a man when he eats 100 g ice in one minute ? Latent heat of fusion of ice is 80 cal/gm.

A coil of enamelled copper wire of resistance 50Omega is embedded in a block of ice and a potential difference of 210V applied across it. Calculate the rate of which ice melts. Latent heat of ice is 80 cal per gram.
