A. evaporation B. condensation C. sublimation D. deposition 相关知识点: 试题来源: 解析 A。解析:“evaporation”是蒸发,液体变为气体的过程叫蒸发;“condensation”是冷凝,气体变为液体;“sublimation”是升华,固体变为气体;“deposition”是沉积,气体变为固体。反馈...
Is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature and/or pressure? What is it called when a liquid becomes a gas? a. condensation b. deposition c. evaporation d. freezing e. melting f. sublimatio...
the increase in hydrostatic pressure with increasing depth is compensated by a hydraulic pressure correspondingly changing with depth in order to keep the total liquid pressure substantially constant over the surface over which the gas is dispersed; this is done by arranging for the ring of liquid ...
Is evaporation of water a physical change or a chemical change? Explain your answer. How do molecules dissolve in water? What atmospheric gas is changing the global climate? What will happen when two water molecules bump into each other when the two oxygen atoms are facing each other? Why?
Gas(g):has not definite shape or volume but can move ___(自由的)most substances can exist in any of the three states depending on the conditions（大部分物质有三种状态）2.分子运动论（考点）___(分子运动论) can explain them and their changing process very well :1.matter is made up of ...
Large interfacial area is achieved in this flow due to a number of factors, related to each other. Three kinds of gas-liquid interface exist in annular flow: 1) Surface of liquid film covered by complicated system of waves, 2) Surface of droplets entrained into the gas core; 3) Surface ...
This appears to have a significant consequence in the phenomenon of LME by either increasing or decreasing the degree of embrittlement. In the context of present theory, this observation is natural. For, by changing the composition of liquid metal, the free electron density in liquid metal is ...
Laminar boundary-layer flows of gas and liquid having a wavy phase-changing interface are analytically investigated to predict the features of their disturbance field. The basic field is approximated to be of linear profiles and perturbed with small wavy disturbances. The rate of phase-change at th...
3,Large storage capacity, the gas storage capacity of a cylinder is equivalent to nearly 30 cylinders of cylinder gas (oxygen,nitrogen). Therefore, the storage space can be reduced, and the bottle changing operation can be reduced. 195L Dewar manufacturer...
So, if fire isn’t a solid, liquid, gas, or a plasma, what does that leave? It turns out fire isn’t actually matter at all. Instead, it’s our sensory experience of a chemical reaction called combustion. In a way, fire...
