1.	One end of a rod is maintained at 50^(0)C and the other end is kept in ice at 0^(0)C. Rate of fusion of ice is doubled. When
Answer» Temperature of hot end is MADE `200^(0)C` and area of cross-section is doubled Temperature of hot end is made `100^(0)C` and LENGTH of rod is made four TIMES area of cross-section is reduced to half ad length is doubled temperature is made `100^(0)C` and area of cross-section and length both are doubled Answer :D
