Problem 4 (10 pts) A certain floor consists of a 4 mm tile laid connected to a subflooring material by an aa h ss p material with negligible thermal resistance. A large heating element maintained at z directly on top of the tile in order to melt the adhesive. The initial temperature of thla subfloor is 305 K. In order to soften the adhesive material between the subfloor an portion of the tile adjacent to the adhesive must be heated to 375 K. The tile and subfloor materia has the equivalent thermophysical properties of a thermal conductivity of 0.19 Wm 998 kg/m3, and a specific heat of 669 J/kgK. the plate, the Heating Element 6 mm thick tile Adhesive Layer Subfloor 4.1. How long does it take for the tile subflooring to reach 375 K? (10 pts) (a) 20.83 s (b) 43.82 s (0) 84.02 s(d) 112.21 s (e) 152.95 s (0) 174.24 s (g) 198.65 s (h) 221.67 s (i) none of these
