乾冰在結冰的魚池裡會怎樣？：英語精讀講義

Hey what's up guys, 語氣意圖

嘿，大家好，

we're back today with another dry ice experiment. 文化背景

我們今天又帶來了一個乾冰實驗。

Dry ice is extremely cold,

乾冰極度寒冷，

but it never gets old. 慣用語

但永遠玩不膩。

You've seen people throwing this stuff in their swimming pool

你們可能見過有人把這東西扔進游泳池裡，

where it makes a really cool effect.

會產生非常酷的效果。

And you might remember last summer I went to the hot springs

你們或許還記得去年夏天我去了溫泉，

and dumped in 100 lb of this stuff

往裡面倒了100磅這玩意兒，

to see how it would react with hot water. 片語搭配

看看它和熱水會產生什麼反應。

But today the ground is frozen over. 片語動詞

但是今天，地面都結冰了。

My fish pond has a thin layer of ice,

我的魚池上也結了一層薄冰，

so I wanted to see what would happen 文法

所以我想看看，

if we tried throwing dry ice into a frozen fish pond.

如果我們把乾冰扔進結冰的魚池裡會發生什麼。

Let's check it out. 片語動詞

我們來看看吧。

But

不過，

Wait, there's more. 表達脈絡

等等，還沒完。

We're going to throw this bucket of dry ice into our fish pond.

我們要把這一整桶乾冰都扔進魚池裡。

And don't worry, 語氣意圖

別擔心，

there aren't any fish in there.

裡面沒有魚。

Now this just froze over last night,

這昨晚才剛結冰，

so the layer of ice isn't that thick. 文法

所以冰層還不是那麼厚。

That means if we throw the dry ice hard enough,

這意味著如果我們用力把乾冰扔下去，

we might be able to get it to penetrate straight through 文法

它可能會直接穿透冰層

down into the water.

掉進水裡。

Is the dry ice going to crack through

乾冰是會砸穿冰層，

or is it just going to skitter around on the top? 用詞

還是只會在冰面上滑來滑去？

This will be interesting to see.

這將會很有趣。

Let's see what happens

讓我們看看

if we just throw one chunk of dry ice in there.

如果僅僅扔進去一塊乾冰會發生什麼。

That's awesome.

太酷了。

But it's going to take a little bit more 用詞

不過要想讓它砸穿，

to get it through.

還需要費點力氣。

And look how

而且你看，

Wow, look at what it's doing to the underneath the ice here.

哇，看它對這片冰層下面造成了什麼影響。

It's actually forming carbon dioxide gas

它其實是在冰層下面

right underneath the ice.

形成了二氧化碳氣體。

That was unexpected.

出乎意料啊。

But I guess it makes sense. 語氣意圖

不過想想也合理。

I'm going to throw another piece down right beside it

我要在它旁邊再扔一塊，

and see if we can get the same effect. 片語搭配

看看是否能產生相同的效果。

Now we need to go all the way through the ice.

現在我們需要徹底穿透這層冰。

There we go. 語氣意圖

成功了。

Oh,

哦，

this is actually going to be really cool.

這絕對會非常酷。

Here goes another one right over here. 片語搭配

這邊再來一塊。

See once the dry ice is under there, 文法

看，乾冰一到了下面，

it releases carbon dioxide,

就會釋放二氧化碳，

but the carbon dioxide gets trapped under the layer of ice 文法

但二氧化碳被困在冰層下面，

and exposes it.

顯露了出來。

Oh man,

天哪，

that's cool.

太酷了。

Look closely at what happens here.

仔細看這裡發生了什麼。

There's an air bubble

有一個氣泡，

and then the carbon dioxide infuses into it

然後二氧化碳注入其中，

and then it rushes out

接著迅速湧出，

and disappears.

消失不見。

What a sweet effect. 文法

多麼美妙的景象。

What's cool about that gas is it's still got that misty, 文法

這種氣體的酷炫之處在於它仍然帶著那種朦朧的，

foggy vapor.

霧狀的水氣。

Let's just go ahead and do the whole bucket. 片語搭配

乾脆把整桶都倒進去吧。

Wow,

哇，

that is cool.

真是太酷了。

I think the coolest thing about this is just the setting.

我覺得這其中最酷的就是這個場景。

With everything frozen over,

到處都結滿了冰，

it kind of looks like one of those foggy English mornings 語氣意圖

看起來就像英國那些霧濛濛的早晨，

with the uh foggy vapor rolling around.

大霧四處瀰漫。

Definitely gives it a different feel 片語搭配

絕對給人一種不同的感覺，

than we had at the hot springs.

和我們在溫泉時的體驗不同。

I could probably like stick my bucket on there.

我甚至可以把桶放上去。

And a bucket just sitting there.

一個水桶就這麼放在那兒。

Random.

挺隨意的。

If you get in close here, 片語搭配

如果你湊近看，

you can see these bubbles going crazy 慣用語

你會看到這些氣泡在瘋狂湧動，

and if you listen carefully,

如果仔細聽，

it almost sounds like they're squealing. 語氣意圖

聽起來幾乎像在尖叫。

You know what's interesting 表達脈絡

你知道有趣的是什麼嗎，

is a lot of the ice looks like it's kind of disappeared now.

現在很多冰看起來好像都消失了。

It wasn't a very thick layer,

冰層本來不是很厚，

but the agitation from all those bubbles

但這些氣泡的劇烈攪動，

must be uh dissipating that ice layer quickly. 文法

肯定在快速消散這層冰。

Look what's happening to the edges of the ice

看看乾冰掉落處周圍

around where the dry ice went in.

冰的邊緣發生了什麼。

It's like reforming a frost layer.

它好像在重新形成一層霜。

It might be water spattering out

可能是水濺出來，

and then refreezing to that ice layer.

然後重新結冰到了冰層上。

Whatever it is, 文法

不管是什麼，

that looks pretty cool.

看起來都很酷。

So that is super cool.

所以這真的超酷。

And of course it makes sense

當然這很合邏輯，

that if you trap dry ice underneath the ice,

如果你把乾冰困在冰層下面，

carbon dioxide is going to build up a layer underneath. 片語動詞

二氧化碳就會在下面聚集形成一層。

Fantastic experiment.

太棒的實驗了。

I'm really glad that we tried that today.

我很高興我們今天嘗試了這個。

So there you have it. 表達脈絡

好了，這就是今天的全部內容。
