Question

What are the main methods of heat transfer from the hot core of Earth to its surface? From Earth’s surface to outer space?
When our bodies get too warm, they respond by sweating and increasing blood circulation to the surface to transfer thermal energy away from the core. What effect will this have on a person in a 40.0ºC hot tub?

Figure 14.30 shows a cut-away drawing of a thermos bottle (also known as a Dewar flask), which is a device designed
specifically to slow down all forms of heat transfer. Explain the functions of the various parts, such as the vacuum, the silvering of
the walls, the thin-walled long glass neck, the rubber support, the air layer, and the stopper.
