考查动词。句意:他们学习粒子在固体、液体和气体中如何运动。空处作how引导的宾语从句的谓语,结合“in solids, liquids, and gases”和首字母提示可推知,动词behave“表现”符合题意,且结合“learn”可知,此处描述经常性的行为,时态应用一般现在时,主语particles为复数,behave也用复数形式。故填behave。反馈 收藏 ...
In a device for separating off solids particles from liquids and gases in flexible single-use containers composed of plastic, multiple filter elements composed of flat, elongate support grilles (3') with filtrate outflow ducts (3'') and with an encompassing filter medium (4), which is closed...
Solid and/or liquid particles are sepd. from a gas stream by dividing the stream and passing the divided streams through a granular silicate which is stable at >300 degrees C. Used for removal of aerosols, dust, tar, smoke from gases. Different components at different temps. (esp. very hi...
- Unlike solids, liquids have particles that are less tightly packed and can move around each other, while gases have particles that are far apart and move freely. Summary: In summary, the arrangement of particles in a solid is characterized by close packing, strong intermolecular forces, and ...
Particles with no pattern and with complete freedom of movement are: A) solids B) liquids C) gases States of Matter: A state of matter is defined as a distinct form by which matter can exist. We differentiate between the states based on the qualitative difference...
The motion of self-propelled massive particles through a gaseous medium is dominated by inertial effects. Examples include vibrated granulates, activated complex plasmas and flying insects. However, inertia is usually neglected in standard models. Here,

Investigations on the flow properties of bulk solids, such as ores, grains and pharmaceuticals, have a wide application in conveyance, processing and storage of these materials1–3. In nature, many important phenomena like avalanches, sandstorms, desert migration, and even traffic flow can be ...
