Crash Course 综合篇 Scientists generally measure pressure with the S.I. unit of force: Newtons per area, meters squared, which is shortened to pascals. 科学家们通常用的国际计量单位 来测量压强: 牛顿平方米,简称帕斯卡。 Crash Course 综合篇 STP means standard temperature and pressure, which according to the lords of chemistry is 0 degrees Celsius and 100,000 pascals or 100 kilopascals. 这个 STP 的意思是——标准温度和压力(简称为标准状况),在化学里它的意思是摄氏0度 和 10万帕斯卡 (或者说100千帕斯卡)。 SciShow 合集 And the strongest spider silk in the world has a tensile strength of about four billion pascals. 而世界上最结实的蜘蛛丝的抗拉强度约为四十亿帕斯卡。 《分钟地球》趣味科普 The pressure from the shockwave would be around 42,340 Pascals. More than enough to completely destroy your eardrums. 冲击波产生的压力约为 42, 340 帕斯卡。 足以完全摧毁您的耳膜。 Crash Course 综合篇 While one hundred kilo-Pascals and one atmosphere are similar, they are not the same. 一百千帕斯卡和一个大气压虽然相似, 但并不相同。 精选英语短文 A pascal is the amount of mass something can take per square meter of material. 帕斯卡是每平方米材料可以承受的质量。 Crash Course Physics 速成课物理 In fact, the average air pressure at sea level is 101 THOUSAND 325 Pascals. 事实上,平均气压 海平面为 101,325 Pa。 Crash Course 综合篇 R equals 8.3145 liter kilo-Pascals per Kelvin mole. R 等于每开尔文摩尔 8. 3145 升千帕斯卡。 Crash Course 综合篇 I said, just now, that it was at STP, which is a pressure of 100 kilo-Pascals. 我刚才说,它是在 STP, 这是 100 千帕的压力。 Crash Course Physics 速成课物理 It's measured in units of Newtons per meters squared, known as Pascals. 它以每平方米牛顿为单位。 被称为“帕斯卡”。 Crash Course 综合篇 Completely by chance, one atmosphere is equal to 101325 pascals, but that's so close that we often just say that one atmosphere is 100,000 pascals or 100 kilopascals. 纯属巧合,1 大气压 = 101325 帕斯卡,但我们一般取整成1大气压 等于10万帕斯卡, 或者说100千帕斯卡。 Crash Course Physics 速成课物理 And 101,325 Pascals x 5 meters cubed, divided by the universal gas constant x 285 Kelvin, is about 214 moles. 和 101,325 Pa x 5 立方米,划分 通用气体常数 x 11 x 等于 214 个原子。 Crash Course Physics 速成课物理 Which means that the pressure at the bottom of the pool is 27,000 Pascals more than the pressure, a quarter of a meter down. 这意味着池底的压力增加了 四分之一米深度处的压力为 27,000 Pa。 Crash Course 综合篇 But since pascals are so tiny we either use kilopascals or we use the pressure here on earth at sea level, that we call one atmosphere or one atm. 但因为帕斯卡实在太小了,我们要么用千帕斯卡,要么用海平面压力来作为单位,我们称之为 1 个大气压, 或者 1 ATM。 Crash Course 综合篇 The pressure inside your car is going to be equal to the outside air pressure, which we’ll take to be the standard atmospheric pressure, or 101,325 Pascals. 你车内的压力将等于外部气压, 我们将其视为标准大气压, 或 101, 325 帕斯卡。 Crash Course Physics 速成课物理 The pressure inside your car is going to be equal to the outside air pressure, which we'll take to be the standard atmospheric pressure, or 101,325 Pascals. 车内压力等于车外空气压力 我们认为它是 101,325 Pa 的标准大气压。 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. |
