heat??????
Ok i want to make little heat. I want to make heat not by making a fire or connecting te + side of a battry to the - side. I can use anything. how can i make a little heat just a little?
put a magnifying glass under a "sun like" lamp wich are sold at flower nurserys but be careful it could make a fier
How can the specific heat becharacterized for a materialthat heats up quickly?
How can the specific heat be characterized for a material that heats up quickly? a. It has a low specific heat. b. It has a high specific heat. c. It is impossible to make this judgment. Logically thinking, if it heats up quickly, it probably also cools down quickly, which means it has a low specific heat. However, I have never found physics to be logical. So. Please help? I really need the answer to the this question. It'll make the rest of the questions in my assignment so much easier.
b. It has a high specific heat. Think of it as heat conductivity. If it is high it is a good conductor of heat. Fiberglass insulation and air ar NOT good conductors of heat.
Is heat retention the same asheat conductivity? Whatmaterials are the greatest atretaining heat?
I understand copper is a great thermal conductor. Does this also mean it holds in heat longer? What materials have the greatest heat retaining qualities?
No, just the exact opposite. Because it's such a good conductor, it carries heat away from itself exceedingly well. But, in general, the materials that prevent heat from moving are not the materials that you wish to have for storing heat. Consider a hot lunch; wouldn'y make much sense to eat stryrofoam, would it? But, you'd use styrofoam to keep your hot lunch hot, or your cold drinks cold. Styrofoam is a great insulator. The best insulators today are vacuum sealed aerogels. You can read the article in Wikipedia. The vacuum prevents thermal conduction, while the sealant prevents radiated heat loss.
