Common feature —irreversible A gas expands to fill the available volume; it does not spontaneously contract into something smaller. A hot body cools to the temperature of its surroundings;it does not spontaneously get hotter at their expense
What determines the direction of...? Can the direction of the spontaneous change be related to some aspect of the distribution of energy We shall see that this is so. Spontaneous changes are always accompanied by a reauction in the quality' of energy, in the sense that it is degraded into a more dispersed, chaotic form Spontaneous, natural changes are simply manifestation of the natural tendency of the universe towards greater chaos 4上一内容下一内容令回主目录 返回 2021/223
上一内容 下一内容 回主目录 返回 2021/2/23 What determines the direction of …? Can the direction of the spontaneous change be related to some aspect of the distribution of energy? We shall see that this is so. Spontaneous changes are always accompanied by a reduction in the ‘quality’ of energy,in the sense that it is degraded into a more dispersed, chaotic form. Spontaneous, natural changes are simply manifestation of the natural tendency of the universe towards greater chaos
