Here are three examples of the transferring of heat given by John Lienhard a M.D. Anderson Professor Emeritus of Mechanical Engineering who attended the National Heat Transfer Conference:
1: Hot water freezes faster than cold water.
When you put an ice cube tray into a frosted over freezer the frost will insulate it. The hot tray will melt the frost and cause the water to have more thermal connection with the cooling coils. The hot water then evaporates into the colder, drier air and there becomes less water to freeze and the evaporation then speeds up the cooling process.
Conclusion: This can be true.
2: Wearing white clothing in the summer is better because black clothing absorbs more heat.
First, they presented skin color and why is it that nature place lighter-skinned people in the colder far North and darker-skinned people on the equator where the energy of the sun is greater.
Football players first began putting black streaks onto their cheeks so that the sun being attracted to dark would help to keep it from their eyes.
Darker skin does absorb more energy from the visible light than lighter skin, but darker skin is more protected from ultraviolet light. Most of the heat from the sun is invisible and comes from infrared radiation; which causes light and dark skin to be within the same color range. Darker skin does not absorb any more heat than lighter skin does.
Conclusion: The color of the clothes you wear makes no difference in regards to giving you more warmth.
3: Metal is colder than wood at the same room temperature.
When your body is warmer than a room it will shed heat and the nerves on your body will be warmer than wood or metal. The ends of you fingers are warmer than wood or metal. Metal conducts heat more rapidly than wood and your finger will feel much colder. On the other hand, if the wood or the metal were much hotter than your hand, the metal will feel much hotter than the wood will.
Conclusion: Metal conducts heat away so it feels colder.
