双语版 TED-Ed 演讲精选 Others might make ideal gas stations for ships headed to deep space, or even host entire human colonies. 其他可以成为前往深空中飞船的理想加油站,甚至容纳完整的人类殖民地。 电台实验室 YORK MILLER: The ideal gas equation. 约克·米勒:理想气体方程。 经济学人 Science and technology Ideal gas laws Newer rules have forced Equinor, Norway's state-owned oil company, to continue cleaning up (see chart 2). 理想的天然气法 新的规则迫使挪威国有石油公司 Equinor 继续进行清理(见图 2)。 Crash Course 综合篇 One mole of any ideal gas takes up 22.4 liters of space at STP, which is a fact that can simplify a lot of calculations. 当气体处于标准状况下时,一摩尔的任何理想气体,体积是22.4升,这可以简化很多运算。 Crash Course 综合篇 But the ideal gas law, much like our culture, has really unrealistic expectations when it comes to size and attraction. 但理想的气体定律, 就像我们的文化一样,在规模和吸引力方面有着不切实际的期望。 Crash Course 综合篇 It's also pretty cool that if you know any 3 things about a gas, you can figure out the fourth using the ideal gas law. 我们能做的酷事是,如果我们知道了任何气体的其中3个属性,通过理想气体定律你可以算出第四个属性。 Crash Course 综合篇 To see all of this in action, let’s consider how the ideal gas law relates to your commute. 为了了解这一切的实际效果, 让我们考虑一下理想汽油定律与您的通勤有何关系。 Crash Course 综合篇 With a little rearranging, we now have the ideal gas law that we know and love. 稍微重新整理一下, 我们现在就拥有了我们所熟知和喜爱的理想气体定律。 Crash Course Physics 速成课物理 – generally an ideal gas in some kind of container – can change according to the first law. 热力学 - 通常是理想气体 在什么容器中- 第一定律。 Crash Course Physics 速成课物理 So the molecules in an ideal gas can actually have a whole range of different speeds. 所以在理想气体中有分子 各种不同的速度。 Crash Course 综合篇 You remember the ideal gas law, it's a combination of three related laws that were discovered by a variety of scientists. 您还记得理想气体定律,它是各种科学家发现的三个相关定律的组合。 Crash Course Physics 速成课物理 Now, we've seen the smooth, even way pressure and volume change with temperature in an ideal gas. 我们看到了温柔温柔的变化方式 它在理想气体中具有压力、体积和温度。 Crash Course Physics 速成课物理 And for every ideal gas -- as long as your units are consistent -- R will be exactly the same number. 对于每一种理想气体… … 如果单位一致 ... R 将完全相同。 Crash Course 综合篇 Let's figure out some stuff! I wonder how much space 1.00 mole of an ideal gas takes up at STP. 让我们弄清楚一些东西! 我想知道 1. 00 摩尔理想气体在 STP 中占据多少空间。 Crash Course Physics 速成课物理 Well, back in 1859, Scottish physicist James Clerk Maxwell used statistical analysis to figure out the distribution of speeds in an ideal gas. 1859 年,苏格兰物理学家詹姆斯 Maxwell 进行了统计分析以找出分布。 Crash Course Physics 速成课物理 So, at higher pressures and lower temperatures, real gases tend to have a bit less volume than ideal gases would. 所以,在高压和低压下,你有气体 真实气体的体积小于理想气体。 Crash Course Physics 速成课物理 To see all of this in action, let's consider how the ideal gas law relates to your commute. 要查看这一切,让我们看看它是如何关联的 理想的气体运送我们。 Crash Course Physics 速成课物理 And in many cases, a real gas is close enough to an ideal gas, that these assumptions apply. 在许多情况下,真实的气体足够接近 充分来自理想,使假设适用。 Crash Course Physics 速成课物理 And, remember, we said that one of our assumptions about ideal gases was that they don't have forces acting between molecules. 我们已经说过,我们对理想气体的假设之一是 是它不强制分子之间的相互作用。 Crash Course 综合篇 It’s a number that connects the pressure and volume of an ideal gas to the number of moles of the gas and its temperature. 它是一个将理想气体的压力和体积与气体的摩尔数及其温度联系起来的数字。 |
