You have just landed a new job with a corner office near the top of a high-rise building. You soon find out why this office was available; it is on the sunny side of the building and becomes uncomfortably hot on sunny days even when it is quite cool outside. Although your college physics course is a distant memory you have an idea of how to solve the problem. You cover the inside of the windows with aluminum foil. This results in
A. a reduction of radiative heat transfer since the shiny aluminum foil has a low emissivity.
B. a reduction of convective heat transfer.
C. a dark room that is just as hot as before you covered the windows.
D. a reduction of conductive heat transfer from the cool outside air to the warm room inside.
