The door of a kitchen oven contains a window made of a single pane of ¼-in. thick Pyrex glass. The interior oven temperature is 550 F and the room air is at 68 F. The combined convective/radiative heat transfer coefficient on the oven interior is 1.7 Btu/hft^2 F , and on the oven exterior it is 0.88 Btu/hft^2 F. A toddler comes by and touches the window. Calculate the temperature of the surface that the child’s hand contacts.
