Answer

Louis,

"Which" is used as a relative pronoun, Basically that means that the word "which" is replacing a noun. This is done not to repeat the same word twice.

For example:

I will visit Brazil tomorrow, from which I will bring many presents.

This is to avoid saying:

I will visit Brazil tomorrow, from Brazil I will bring many presents.

So you just have to pay attention to the preposition that would go with a noun and use "which" to replace the noun.

Examples:

Water has to be heated to a certain point, at which (at a point) it will start boiling.

We have to enter the house, out of which (out of the house) those men came out.

This situation has caused me a problem, which (this problem) I cannot resolve.

I hope this helps.
