One end of a copper rod of length 1m and area of cross section `4.0 xx 10^(-4) m^(2)` is maintained at `100^(@)C`. Neglecting the loss of heat to the surroundings find the mass ice melted in 1 hour. Given `K_(Cu) = 401` watt/m - k and `L_(f) = 3.35 xx 10^(5) J//kg`.   img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/BSL_XI_RT_P11_E01_480_Q01.png" width="80%"
