A 6.25 kg block ice at 0 degrees Celsius is being warmed on a glass stove top. The thermal conductivity of the glass is 1.00 W/ (m K) and the glass is 0.50 cm thick. If the radiator plate underneath the glass raises the temperature of the bottom of the glass to 125 degrees Celsius, how long would it take to completely melt the ice? Assume the ice remains a solid rectangle with a square base of side 15 cm as it melts.
B. What is the rate of entropy change in Joules/ Kelvin/ seconds of the melting ice?

The legs are fabricated at 20°C to a height of 0.10000m. After the detector is in place, the scientists adjust the temperature of the legs in order to compensate for the compression due to the weight of the detector. If they would like the final height of the legs to be 0.10000m, what should be the temperature of the legs? For aluminum, Y = 7×101º, a = 2.4×105 %3Darrow_forward

You fill it with water and put it into the freezer. It is effectively a perfect insulator, blocking all heat transfer, except on the top. After a time, ice forms on the surface of the water. The liquid water and the bottom surface of the ice, in contact with the liquid water, are at 0 °C . The top surface of the ice is at the same temperature as the air in the freezer, −18 °C. Set the rate of heat flow through the ice equal to the rate of loss of heat of fusion as the water freezes.
