- 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?A wall consists of a concrete layer on the outside and a wood layer on the inside. W The concrete on the outside is 10.00cm thick and has a thermal conductivity of 0.500 m.K W The wood on the inside is 3.00cm thick and has a thermal conductivity of 0.180 m·K The outside temperature is 38.00°C and the inside temperature is 22.00°C. The surface area of the wall is 25.0m². а. What is the rate of heat flow through the wall? b. What is the temperature in between the concrete and the wood?A square steel bar of side length w = 0.14 m has a thermal conductivity of k = 14.1 J/(s⋅m⋅°C) and is L = 2.4 m long. Once end is placed near a blowtorch so that the temperature is T1 = 77° C while the other end rests on a block of ice so that the temperature is a constant T2. a) Input an expression for the heat transferred to the cold end of the bar as a function of time, using A = w2 as the cross-sectional area of the bar.
