A. Sublimation B. Evaporation C. Condensation D. Distillation 相关知识点: 试题来源: 解析 A。固体直接变为气体的过程称为升华(Sublimation)。“Evaporation”是蒸发,指液体变为气体;“Condensation”是冷凝,气体变为液体;“Distillation”是蒸馏。本题描述的是固体到气体,所以是升华,选 A。反馈...
The process when a solid changes directly to gas is called [{Blank}]. State the process by which solids change directly to gases and from gases to solids. What is it called when a gas turns into a solid for a phase change? Describe a situation where a ...
The function of the regenerator is to use gas generator exhaust vapors to preheat the air exiting the air compressor, thus reducing the amount of fuel required by the gas turbine. Figure 6.1.5 also shows the changes of gas temperature, pressure, energy, and the horsepower produced in the ...
The transport options preferred by governments and companies not only must take the economic risks into account but also consider the negative effects of possible terrorist activity, political changes, and trade embargos over long periods of time. Thomas and Dawe (2003) covered many of the essential...
Fig. 4: Dominance ratio variations induced by changes in the underlying hydrologic conditions. a dominance ratio as a function of the stream discharge Q in the reaches A (light gray), B (gray) and A* (black). Circles represent the observed values of r, the dashed lines show a linear pi...
This article presents a structure-based modeling approach to optimize gas evolution at an electrolyte-flooded porous electrode. By providing hydrophobic islands as preferential nucleation sites on the surface of the electrode, it is possible to nucleate and grow bubbles outside of the pore space, fac...
data.Unfortunately, the complexity of most solid surfaces —especiallythose of industrial importance —makesitdifficult to obtain any independent assessment of the physical significance of the quantities derived (e.g. theabsolute magnitude of the surface area and pore size).A number of attempts have ...
Equation (4.16) is based on Boyle’s law and Charles’s law. The above relates the change in ideal gas volume to the changes in prevailing pressure and temperature, respectively. Furthermore, Equation (4.16) is referred to as the equation of state for an ideal gas. ...
To optimize the performance of these engines with NG, in each generation of engines, the manufacturers have been continually incorporating changes so as to maximize its power. Currently, the technological advancements incorporated to the feeding and combustion systems in engines of this type have ...
