21 Which behaviour of the particles in a gas is incorrect? C A The particles are very far apart. B The particles move at high speeds. C The particles are arranged in regular patterns. D The forces of attraction between the particles are negligible. 相关知识点: 试题来源: 解析 C 反...
A process for producing a stream of fine granular particles in a gas flow, comprises dosing the particles into a gas flowing axially at raised pressure, and then changing the gas stream into a free jet. The particles are dosed using a number of concentrically arranged supply points which run...
D The argument that human -caused carbon emissions(排放) are merely a drop in the bucket compared to greenhouse gases generated by volcanoes has been making its way around the rumor mill for years. And while it seems to be reasonable, the science just doesn't back it up.According to the...
sorting, and the probability cumulative curves are mainly two-stage dominated by suspension components. The C-M diagram shows that the Xibozhang section consists largely of uniformly suspended deposits, belonging to typical meandering river deposits. Comparing the measured section with the loess section ...
The natural pore structures of shale gas reservoirs are the core factors affecting the sorption and/or storage capacity and production efficiency of gas plays (Guo et al., 2015a, Guo et al., 2015b). For the purpose of characterizing the ultra-fine pore structure, often associated with ...
Additional answer space if required:(b)0.24mol of gas is contained in a cylinder as represented in Fig. 38.2. The gas is trapped by a disc of negligible mass so that the pressure in the cylinder is equal to the atmospheric pressure outside the cylinder. The disc can move up and down ...
System for charging particles entrained in a gas stream A system for charging dust and the like particles entrained in a gas stream and which are to be electrostatically precipitated. An emitter electrode is disposed in the gas stream for producing ions of one polarity which charge particles .....
(a)(i)Methane(iii)Natural gas is a mixture of covalent compounds which have a simplemolecular structure.There are weak intermolecular/ van der Waals forces of attraction betweenthe molecules,hence little energy must be supplied to overcome these forces of attraction,and natural gas has a low boi...

The concepts of concentration of adsorbed molecules on the surface of aerosol particles and diffusion of adsorbed molecules in the liquid phase are used for determining the importance of the adsorption/absorption mechanisms. The model calculations showed a qualitative agreement with available experimental ...
