# Thread: As versus When

1. ## Re: As versus When

Hello,
There is a saying: "correlation doesn't mean causation".
If I have understood your explanations we tend to use As for correlation.
What about causation ?
( I'm sorry for using the most abused example but I couldn't come up with something more simle.)

If you boil water, the water vapour in the air.
Is it equvalent to :
As you boil water, the water vapour in the air.
or
When you boil water, The water vapour in the air.

Is there any difference in meaning ?

Cheers,

Then you've misunderstood mine, unless you're basing this on David's.

"As you boil water, the water turns into vapour in the air."
(Pardon me for adding a few necessary words).
Yes, this is the meaning of "As" that David was asserting. Apparently he regards it as the only way to use "As".
"When" means a similar thing here", though it doesn't emphasise the simultaneity of the boiling and the vapourising.
"If" doesn't enter into it. (The water could be evaporating).

How do you feel about "As the water was boiling, I added some salt".

Thank you for that, that is one of the things I like about this website.

I went through all the posts again and again. I think I need some more time to fully understand what it is all about.
Moreover I don't get why "If" doesn't enter into it.

Apparently, according to David's explanation, you were going to grow some salt crystals.

Cheers,

You can say "If you boil water, the water turns to vapour in the air.
And it can mean the same as "When you boil water, the water turns to vapour in the air."
But "if" doesn't enter into the original question, because it doesn't help decide whether "as" or "when" is correct in a time clause such as:
"___ he was walking down the street, he ran into Jane."

OK, if you like you can take these normal English examples from a Google search of the web. They all the same syntactic construction. "As he was walking", + clause in simple past.

Dear Teachers,

It was confirmed by a mail I received yesterday from the authorized person at Sabanci University that the question was checked and found to be erroneous also by the university teachers and would be corrected as soon as on the updated web page.

Regards and thanks for your time and efforts.
