At what temperature is the rms speed of helium molecules half its value at STP (0 C, 1.0 atm)? If 1.30 mol of gas at a temperature of -140 degrees C fills a 3.80 L container. What is the gas pressure? A storage tank at STP contains 18.5 kg of nitrogen. What is the volume of ...
有没有物理帝帮忙算个得数The rms speed of O3 is 1780 m/s at a given temperature.Find the rms speed of N2 at this temperature?m/s 答案 首先你要搞清楚一个概念,物体温度的直接表现是分子的剧烈运动,也就是动能.当物体接近-273度的时候,物体的分子运动就会全部停止,就是动能为0.根据能量公式 E=1...
11. (II) Calculate (a) the rms speed of an oxygen molecule at 0 C and (b)determine how many times per second it would move back and forth across a 7.0-m-long room on the average, assuming it made very few collisions with other molecules. 相关知识点: 试题来源: 解析 11. (a)...
We selected to grow SAMs from the vapour phase using a uniquely designed atomic layer deposition(ALD) reactor to allow excellent control of reaction conditions (precise OTS dosing, water content, temperature and so on) and continuous in situ observation of SAM growth with operando spectroscopic elli...
Moreover, a temperature sensor is integrated into the device, which allows additional trend monitoring of the temperature.Learning mode and alarm thresholdsEvery machine has its own characteristic vibration level, which is why the alarm thresholds need to be adjusted specifically to the machine during...
