A copper vertical plate that is 0. 305 m tall and 1. 5 m wide separates two large air spaces. The air space at the left is at 50 C and 746 mm Hg, while the air space at the right is at 4 C and 735 mm Hg. Required results: What is the rate of heat transfer Q from the hotter air space to the cooler air space? Find the temperature of the copper plate.
