Ahh. The chain reaction.
.
You know when you are surfing the web, your parents tell you, or you surf the web, that you see some things like "STOP GLOBAL WARMING?"
.
Yep, I have, at least.
.
Well, let's see about the chain reaction...
.
You see, where does our energy come from?
.
Yes, windmills and solar cells...
.
but also nuclear and power plants, no?
.
The power plants emit carbon dioxide that contribute to global warming.
.
Now, cars do the same. One car may not seems like a lot of carbon dioxide...
.
.
But... this many cars multiplied by 9 trillion times 9 trillion and much more... is...
<span>
</span>.
Well, you know the difference.
.
They contribute to global warming over a period of time, slowly, because they emit carbon monoxide/dioxide.
I think that it would be the breakdown. Hope this helps!
Answer: The given compounds are arranged according to decreasing boiling point as
.
Explanation:
The temperature at which vapor pressure of a substance becomes equal to the atmospheric pressure is called boiling point.
Stronger is the intermolecular forces present the atoms of a molecule more heat will be required by it to break the bond between its atoms. Hence, more will the boiling point of the molecule.
In
(methanol), there is hydrogen bonding present which is a stronger force. So, it will have highest boiling point as compared to
and
.
In
(chloroform), there is more electronegative atom attached (Cl) is attached to less electronegative atom (C and H). So, electrons are more pulled towards the chlorine atom. So, boiling point of
is more than methane
.
Thus, we can conclude that given compounds are arranged according to decreasing boiling point as
.
Answer:
— 159.6°C
Explanation:
Data obtained from the question include:
V1 (initial volume) = 960L
T1 (initial temperature) = 38°C = 38 + 273 = 311K
V2 (final volume) = 350L
T2 (final temperature) =?
Since the pressure is constant, then Charles' law is in operation. Using the Charles' law equation V1/T1 = V2/T2, we can easily obtain the final temperature as follow:
V1/T1 = V2/T2
960/311 = 350/T2
Cross multiply to express in linear form.
960 x T2 = 311 x 350
Divide both side by 960
T2 = (311 x 350) /960
T2 = 113.4K
Now let us convert 113.4K to a number in celsius scale. This is illustrated below:
°C = K — 273
°C = 113.4 — 273
°C = — 159.6°C
Therefore, the container will have a volume of 350L at — 159.6°C
