- 1. Do all hot objects radiate light? If hot water is placed in a vacuum in total darkness will it radiate heat? Recall that heat is detected through night-vision goggles. These devices "see" infra-red light emitted by hot objects. This is evidence that heat is a part of the spectrum and therefore it can travel through a vacuum just as the other components of light. If so, then heat should travel as fast as light through a vacuum. It should travel just as fast through air. Why then does the air gap inside the thermos bottle retard the loss of heat from the hot water inside? 2. The coefficient of linear expansion of aluminum is 0.000023/C.
