We consider Bose-Einstein condensation of an ideal Bose gas with an equal mixture of 'Rashba' and 'Dresselhaus' spin-orbit interactions and study its effect on the critical temperature. In uniform Bose gas a 'cusp' and a sharp drop in the critical temperature occurs due to the change in ...
极低温时气体的液化趋势也无法忽略不计,此时需要添加一个概念:蒸汽,就是气液混合物,在温度极低的时候部分分子间距缩小到液体的范畴,从而实际v也要比计算出来的体积小图片中 从右上到左下温度减小 灰色区域为液体存在的区域,到达区域的条件是温度到达critical temperature,否则无论如何增加p都不会压缩为液态。灰色区域...
The critical temperature of Bose-Einstein condensation at minimum momentum state for weakly interacting Bose gases in a power-law potential and the deviation of the critical temperature from ideal bose gas are studied. The effect of interaction on the critical temperature is ascribed to the ratiao ...
Estimation of Critical Properties Critical pressure and temperature are defined as the pressure and temperature at the critical point. For a gas mixture, the critical point is defined as the point (pressure and temperature) at which all properties of the liquid and the gas become identical. It ...
In Eq. (7) the total number N of Bosons is a function of temperature T, chemical potential µ and interaction constant g, namely N = N(T, µ, g). Setting g = 0 we have the number of particles for an ideal Bose gas. In this case, to find the critical temperature T (0)...
(a) CH4 (b) O2 (c) CO2 (d) NH3 (e) Ne. Critical Temperature: The critical temperature is a temperature in which a substance can not exist as a liquid irrespective of how much pressure is applied. The critical temperature is given by:Tc=8a...
Gases can be changed to liquid (a process called liquefication) but this is harder as the temperature of the gas is increased. An increase in temperature causes an increase in the kinetic energy of the particles and slowing down the particles (necessary to liquefy the...
Liquefaction of gases takes place at a temperature either equal to critical temperature or at a temperature lower than critical temperature. Also at the critical temperature, the pressure would be equal to critical pressure.
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
Plates were incubated at room temperature for 2 d, then at 4 °C for 4 d and colonies counted. Microbial community profiling 16S rRNA gene amplicon sequencing was used to estimate the relative abundance of bacterial taxa. Total DNA was extracted from phyllosphere and input communities ...
