| Text | #433 (Length: 429 characters) Convection also plays a minor role because of the relative thinness of the air layer and the presence of the upper cardboard heat shield. The insulation properties of the cardboard play a major role, since they serve to minimize the temperature gradient across the airspace. By studying the cooling of pizza in the gravity free environment of the space shuttle, we could more exactly determine the importance of convective flows. |
