Gasoline produces per gallon something like close to a hundred million joules.
国际单位制中的能量单位是什么，焦耳。
蛋白含有约15卡路里（60千焦耳）。
旋转动能是，2亿焦耳，每个飞轮都是。
And that kinetic energy of rotation is, then, a whopping 200 million joules in each of those rotating flywheels.
对单个原子，就是10的负18次方焦耳。
150焦耳足够杀死你。
在大多数领域，这个单位已经被“焦耳”取代。
回想一下焦耳膨胀。
焦耳的想法是，重力对水，做了功。
And the idea was that gravity did work on the water and falling, and that work led to the generation of heat.
你们看到那边上面写着，一卡路里等于4。2焦耳。
You see there on the top there that one calorie is 4.2 joules.
所以这是一个不可逆过程，焦耳-汤姆逊。
一个较大的蛋黄含有约60卡路里(250千焦耳)。
A large egg yolk contains approximately 60 Calories (250 kilojoules).
我们会发现，你们也会发现，理想气体的焦耳系数是零。
And we saw that, you saw that the Joule coefficient for an ideal gas was zero.
如果再往下看1s层，是一摩尔20兆焦耳。
每一个光子有，2,84乘以10的- 19次方焦耳。
So for every photon we have 2.84 times 10 to the -19 joules.
当我把所有这些相加，我想我大约消耗4亿，焦耳每天。
And when I add that all up, I think I consume roughly 400 million joules per day.
为一千瓦时电，就是四百万焦耳，我只花区区10美分。
For one kilowatt-hour of electricity, which is four million joules, I pay only a lousy ten cents.
这可能，大概消耗30瓦，30焦耳每秒是我大概的猜测。
This is probably this probably consumes 30 watts, 30 joules per second is my rough guess.
你每秒钟大约辐射，100焦耳——100瓦。
That is about 100 joules per second that you radiate 100 watts.
我们算出的能量是，2,84乘以10的- 19次方焦耳。
And what we end up with for the energy then is 2.84 times 10 to the -19 joules.
现在地球上60亿人，大约4乘以，10的20次方焦耳每年。
00000 billion people now on Earth is about four times ten to the 20 joules per year.
这和你的人体相比较，人体每秒发出一百焦耳，每秒100瓦。
Compare that with your body, which generates a hundred joules per second every second 100 watts.
10米要乘以，因为我做了5次，所以做了35000焦耳的功。
The ten meters have to be multiplied by five, because I do it five times, and so I get 35,000 joules of work that I do.
所以这个不可逆过程,也就是焦耳-汤姆逊过程,是一个等焓过程。
So this irreversible process this Joule-Thomson process, is a constant enthalpy process.
这意味着能量等于，6,626乘以10的- 34次方焦耳每秒。
That means our energy is equal to 6.626 times 10 to the -34 joules times seconds.
是的，它们是不同的但它们大致上，都是一摩尔一兆焦耳。
Yeah, they're different but they are roughly on the order of about 1 MJ per mole.
