Conditional type 1:

"IF" introduces a real possibility which can happen in the future.

If (verb in present simple), (verb in future simple).

Conditional type 2:

"IF" introduces an unreal condition in the present which may not happen at all.

 If (verb in past simple), (would + infinitive)

conditional type 0:

in this type of condition if means almost always the same as when .the condition can be true at any time .

Example:

if you put water on the solar cooker, it boils.

when  you put water on the solar cooker, it boils.

rule:

if+... present simple...will/won't.

A:look at the clouds,if it rains,we'll get wet .

B:Ok, let's take our umbrellas.

if+...present simple...would/wouldn't

A:what would happen if it didn't rain again?  

B:if it didn't rain again, the area would become a desert.

in the first example A and  B  are talking about a real possibility .

A predicts something which can happen in the future. 

We do not use will in the if-part of the sentence, even though it refers to the future; e.g. if Ipass the Baccalaureat, Iwill be happy .  (not if Iwill pass...).

in the second example ,A and B are talking about an unreal situation .it may not happen at all .they are talking about the situation now and not in the past.

Note: We generrally say, if Iwere you... and not if I was you...
