Please help me with these questions An element on a hot stove is maintained at a constant temperature of Thot = 105 °C and a pan is placed on the element. The base of the pan can be taken to be a uniform circular layer of diameter 15 cm and thickness 7.0 mm, and with a thermal conductivity of 15 W m-1 K-1. a. The air above the pan comes into thermal equilibrium with the element. Write down the temperatures on the top and bottom surfaces of the pan and the rate of heat flow through the pan. Use the zeroth law of thermodynamics to explain your answer. A fan is then switched on so that the air above the pan is maintained at Tcold = 20 °C, and the system reaches a steady state. b. Identify the heat transfer mechanism that is being used to maintain the air at Tcold. c. Calculate the rate of heat transfer through the pan. A 3.0 mm thick layer of soup is added to the pan and the system again reaches a steady state. The temperature at the boundary between the pan and the soup is 95 °C. d.…

A brass plate has a circular hole whose diameter is slightly smaller than the diameter of an aluminum ball. Ifthe ball and the plate are always kept at the same temperature,(a) should the temperature of the system be increased or decreasedin order for the ball to fit through the hole? (b) Choose the bestexplanation from among the following:I. The aluminum ball changes its diameter more with temperature than the brass plate, and therefore the temperatureshould be decreased.II. Changing the temperature won’t change the fact that the ballis larger than the hole.III. Heating the brass plate makes its hole larger, and that willallow the ball to pass through.

Please show all steps not Ai generated they have been wrong and I need to understand whats goin on. A steel sphere (AISI 1010), 100 mm in diameter, is coated with a dielectric material layer of thickness 2 mm and thermal conductivity 0.04 W/m • K. The coated sphere is initially at a uniform temperature of 500°C and is suddenly quenched in a large oil bath for which To = 100°C and h = 3000 W/m • K. Estimate the time required for the coated sphere temperature to reach 150°C. Hint: Neglect the effect of energy storage in the dielectric material, since its thermal capacitance (pcV) is small compared to that of the steel sphere.
