A very large piece of carbon steel (? = 7854 kg/m3 , ? = 60.5 W/m·K, ?? = 434 J/kg·K) is initially at a temperature of 40°C. Suddenly, the flat surface of the steel is pressed into contact with an object at a temperature of 20°C. Which of the following is closest to the temperature of the steel at a location 10 mm from the flat surface after 0.5 s?

A thick steel slab (ρ= 7800 kg/m3, c= 480 J/kg·K, k= 50 W/m·K) is initially at 300°C and is cooled by water jets impinging on one of its surfaces. The temperature of the water is 25°C, and the jets maintain an extremely large, approximately uniform convection coefficient at the surface. Assuming that the surface is maintained at the temperature of the water throughout the cooling, how long will it take for the temperature to reach 50°C at a distance of...
