1. Discuss the modes of heat transfer that determine the equilibrium temperature of a space shuttle when it is in orbit. What happens when it re-enters the earth's atmosphere?
2. A closed plastic container, used to serve coffee in a seminar room, is made of two layers with an air gap placed between them. List all heat transfer processes associated
with the cooling of the coffee in the inner plastic vessel. What steps do you consider necessary for a better container design so as to reduce the heat loss to ambient.
