Heat- and mass transfer takes place whenever flow materials contact each other directly. The transfer is the more efficient the greater the contact surface between the contacting media. Therefore, the cooling water in wet cooling towers is supplied to large surface units with liquid withdrawing means on which a thin film is formed a...
In solids, heat transfer occurs by conduction; in fluids (gases and liquids), heat transfer proceeds primarily by convection. When a liquid or a gas is heated, the molecules near the heat source gain energy and tend to move away from the heat source. Therefore, the fluid near the heat so...
Conduction heat transfer is the transfer of heat through matter (i.e., solids, liquids, or gases) without bulk motion of the matter. From: Bio-Engineering Approaches to Cancer Diagnosis and Treatment, 2020 About this pageSet alert Discover other topics ...

选C是过去分词做状语的用法,表示条件,即“如果被加热,液体能变成气体。”而B项是不定式结构,虽能做状语,但其本身常含有将来的意味,而句中所述情况为自然真理,并不依时间为转移,所以要选C,而不选B。
)___,liquids can be changed into gases.A.Heating B.To be heated C.Heated D.Heat本题要选一分词作为状语.现在分词表主动,正在进行的;过去分词表被动的,已经完成的.对于液体来说是加热的受动者,是被动的,因而选C.它相当于一个状语从句 When it is heated,…、为什么不...
"That's all it is. Heaters and soup. " Most of the injuries were to hands and wrists, and most came from contact with hot liquids or from touching hot objects. Not only do small children not realize the danger posed by hot objects; their skin is much thinner than that of adults. ...
Much of the initial interest in the development of polymer heat exchangers was stimulated by their ability to handle liquids and gases (i.e. single and two-phase duties), their resistance to fouling and corrosion, and their possible use in both humidification and dehumidification systems. Perhaps...
