One plate (with k=15W/m-K, p=6500kg/m3, cp=450J/kg-K, thickness of 0.2m, and initial temp of 465K) is pushed against another plate (with k=10W/m-K, p=4000kg/m3, cp=525J/kg-K, thickness of 0.2m, and initial temp of 375K) both having their opposite sides insulated. After a total of 115 seconds passes (since the plates touch), what is the temperature of the hotter plate's exposed surface?
