第四輪翻譯

By contrast,low-quality energy is dispersed and has little capacity to do useful work.An example is heat dispersed in the moving moclecules of a large amount of matter(such as the atmosphere or an ocean)so that its temperture is low.The totalamount of heat stored in the Atlantic Ocean is greater than the amount of high-quality chemical energy stored in all the oil deposits of Saudi Arabia. yet because the ocean's heat is so widely dispersed, it cannot be used to move things or to heat things to high tempertures.

相較之下,低的能量被分散且擁有很小的能量作功.例如數量龐大的物質在一群移動的分子裡被分散(如大器或海洋)以至於他們的溫度低.雖然大西洋所儲存的熱量比儲存在阿拉伯地底下的石油還多.但是由於海洋太寬已至於熱量被分散了,所以它不能用來移動東西或加熱物質至高溫.
