Answer» 1)Heatis a form of energy that can be transferred from one object to another or even created at the expense of the loss of other forms of energy. To review, temperature is a measure of the ability of a substance, or more generally of any physical system, to transferheatenergy to another physical system. 2)Heat conduction(orthermal conduction) is the movement ofheatfrom one solid to another one that has different temperature when they are touching each other. For example, we can warm our hands by touching hot-water bottles. ... Other ways to transferheatare bythermalradiation and/or convection. Convectionisheattransfer by mass motion of a fluid such as air or water when the heated fluid is caused to move away from the source ofheat, carrying energy with it.Convection above a hot surface occurs because hot air expands, becomes less dense, and rises (see Ideal Gas Law) |
