Do molecules move faster when heated? Withan increase in temperature, the particles gain kinetic energy and move faster. The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature. Do...
【题文】 Atoms and molecules in the air move constantly. 【小题1】 In high-pressure systems, the molecules inside the system move faster than those that surround it. The opposite occurs in low-pressure systems, where the air inside the low is moving more slowly than in the surrounding area...
A. They become arranged more regularly. B. They become smaller. C. They move much closer together. D. They move faster. 相关知识点: 试题来源: 解析 A 当水结冰时,水分子会形成一个有序的晶格结构,排列更加规律。因此,正确答案是 A。其他选项错误,因为水分子的大小不会改变,结冰时水分子的间距会...
新细节 信息提取 Do you know which move faster, hot water molecules or cold ones? Drop some (use colouring(食用色素) in cold water and hot water, and watch carefully!What you'll need:• Two glasses• Water (cold and hot)• Food colouring___ ...
[answer] (1) where the sun is drying, the temperature is high, the molecules move faster, and the water evaporates quickly, so the clothes dry quickly. (2) there is a large gap between the gas molecules. When the gas is pressed, the space between the gas molecules decreases, so the ...
In high-pressure systems, the molecules inside the system move faster than those that surround it. The opposite occurs in low-pressure systems, where the air inside the low is moving more slowly than in the surrounding are...
Is it worth it Two things experts consider when judging any risk are : 1) How likely the event is ; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 400, 000 years. Sounds pretty rare-but...
(ii) Students' answers should include the following: • rate of change would be (almost) linear/ constant/ eq • (changes) would occur faster/eq • the idea that (overall) movement of molecules would not stop when concentrations equal, e.g. equilibrium would not be ...
Methane molecules fluctuate around one methane which later becomes the central gas molecule, and when several methanes move into the region within 0.8 nm of the potential central methane, they act as directional methane molecules. Two neighbor directional methanes and the potential central methane...
