Our star is 2 octillion tons of hot hydrogen gas emitting 400 septillion joules of energy every second.

这颗恒星由2万亿重的热氢气组成的，它每秒释放出400 ^ 10万亿焦耳的能量。

Food also contains energy, which is measured in calories or joules.

食物也含有能量，以卡路里或焦耳作为单位来衡量。

One joule per second equals one watt.

1 焦耳/秒 = 1 瓦特。

For any numbers enthusiasts watching, that's 430 quintillion joules  striking the earth every single hour.

对于任何数字爱好者来说，每小时都有 430 兆焦耳撞击地球。

Work done in joules is force multiplied by distance.

以焦耳为单位所做的功是力乘以距离。

A cosmic ray detected on October 15th, 1991 had an energy of 51 joules.

1991 年 10 月 15 日探测到的宇宙射线能量为 51 焦耳。

Note that the standard enthalpy is in kilojoules while the standard entropy is in joules per Kelvin.

请注意，标准焓的单位是千焦耳， 而标准熵的单位是焦耳每开尔文。

Because, you know how we just said that Joules are the units of work?

因为，你还记得我们说过 就在不久前，焦耳用作工作焦耳？

We figured out that you did 250 Joules of work on the box when you moved it 5 meters.

我们发现您应用了 250 焦耳的功 当你将它移动五米的距离时，它就会出现在盒子上。

This is enough energy to continuously power 200,000 homes Food also contains energy, which is measured in calories or joules.

这足以为 200,000 个家庭持续供电 食物也含有能量，以卡路里或焦耳来衡量。
