If we take hydrogen peroxide in the liquid state, it can break down to form water and oxygen.
如果我们有一些液态的过氧化氢,它会分解成水和氧气。
Let's take salt, solid, and dissolve it in a bunch of liquid water.
我们把食盐晶体,溶解在一些水中。
And, in fact, if you take the jaws of a powerful magnet and pour liquid oxygen in between the jaws, the oxygen will stop and will sit in the jaws.
实际上,如果你用一块,具有较强磁力的颚型磁铁,然后把液氧倒在颚型磁铁的中间,氧气会停在颚型磁铁中。
We'll talk specifically about how many calories people are consuming in liquid form which has gone way, way up.
我们将具体谈论人们从饮料中,摄取的卡路里量,这个数字直线上升
So the triple point is liquid solid, gas, all in equilibrium.
气态,固态,三相平衡,你可能会想。
Higher entropy basically because you're forming molecules of gas where there weren't any before, and there's more disorder in the gas phase than in the liquid. That is, the gas phase molecules have more freedom to roam.
高的熵是因为,我们产生了以前不存在的气体分子,气体的无序程度比液体大,换句话说,气相的分子,有更多的到处游荡的自由度。
Normally this is used for a reaction in the condensed phases and liquid usually.
通常它是用于凝聚态,液体相的反应,这是一个恒压量热计。
Your body interprets liquid calories different than it does calories in solid food.
你身体以不同的态度,对待饮料和固体食品中的卡路里
And the triple point of water is 16K that temperature and pressure - there's a unique temperature and pressure where water exists in equilibrium between the liquid phase, the vapor phase, and the solid phase.
与水的三相点,我们定义它为273。,水的三相点,是一个特定的温度和压强,可以使水的液态,气态和固态三相共同达到平衡,三相点是液态。
We use a liquid helium. And so in order to make a liquid helium, you can't take helium at room temperature and do this, because if you did, you would just heat it up, because the room temperature is above the inversion temperature, so Joule-Thomson would heat up the helium.
为了得到液氦,不能再常温,做这个实验,否则就是加热氦气,因为室温高于它的转变温度,所以焦耳-汤姆孙,实验会加热氦气。
