Crash Course 综合篇 Well, let's see what the gas law can tell us. 好吧,来看看理想气体定律能告诉我们什么。 当月 CNN 10 学生英语 2021年10月合集 Haiti's government has a gas law that's contributing to this crisis. 海地政府的天然气法导致了这场危机。 双语版 TED-Ed 演讲精选 Now, Boyle's gas law states that the volume of a gas is inversely related to pressure. 波义耳定律描述的是气体的规律,它讲的是气体体积与其压强成反比。 TED演讲(音频版) 2017年9月合集 And then there's spin and gas laws and viscosity. 然后是自旋和气体定律以及粘度。 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 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 综合篇 But here's the cool part: That exact same research also led to an important gas law. 但这是很酷的部分:完全相同的研究也导致了重要的气体定律。 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 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 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 And we went over the ideal gas law, and how to use it to find the number of moles of air in your car. 我们回顾了理想气体定律,以及如何 用它来找出车内的原子数。 Crash Course Physics 速成课物理 Well, according to the ideal gas law, the amount of gas in moles is equal to pressure x volume divided by temperature x the universal gas constant. 根据理想气体定律,气体的体积以原子为单位 等于压力 x 体积除以热量 x 气体常数。 Crash Course 综合篇 Through the ideal gas law, the number of moles is directly related to the pressure of gas it exerts, as long as the volume and temperature remain constant. 通过理想气体定律,只要体积和温度保持不变,摩尔数与其施加的气体压力直接相关。 Crash Course 综合篇 One last thing: remember that STP, or Standard Temperature and Pressure, is 0 degrees Celsius and 100 kilo-Pascals, but gas law equations are done in Kelvins, not degrees Celsius, so we'll call it 273.15 K and 100 kilo-Pascals. 最后一件事:请记住, STP,或标准温度和压力, 是 0 摄氏度和 100 千帕,但气体定律方程是用开尔文计算的, 而不是摄氏度, 所以我们称它为 273. 15 K 和 100 千帕.

Gas laws(重定向自Gas law)
This article outlines the historical development of the laws describing ideal gases. For a detailed description of the ideal gas laws and their further development see ideal gas law. The gas laws were developed at the end of the 18th century, when scientists began to realize that relationships between the pressure, volume and temperature of a sample of gas could be obtained which would hold to a good approximation for all gases. Gases behave in a similar way over a wide variety of conditions because they all have molecules which are widely spaced, and the equation of state for an ideal gas is derived from kinetic theory. The earlier gas laws are now considered as special cases of the ideal gas equation, with one or more of the variables held constant. |
