1. A cubic block with 10-cm sides (p = 5000 kg/m, cp = 500 J/kg K, k = 10 W/m K) is at an initial temperature of 150C. The whole block is exposed to ambient air at 30C with a heat transfer coefficient (h) of 20 W/mK. Find the temperature at the center of the block at t= 10s. Show your working steps clearly. Justify all the assumptions you make. (20 points) 10 cm 10 cm 10 cm
