A bar of cross-sectional area 0.02m2, thermal conductivity 80mW and an unknown length is insulated apart from being in contact with a heat reservoir of temperature 523 K at one end and a very large block of ice at the other. The ice is being melted at a rate of 0.02minkg. 4. What is the magnitude of the rate of energy flow from the heat reservoir to the ice? (a) ∗∗∗110 W (b) 330 W (c) 990 W (d) 2200 W (e) 6600 W 5. What is the length of the bar L ? (a) 0.8m (b) 1.2m (c) 2.7m (d) *** 3.6m (e) 7.5 m
