Grammar / Conditional Type 0

Use to express a general truth or a scientific fact. In this type of conditional, we can use when instead of if.

When the if-clause precedes the main clause, we use a comma to separate the two clauses.

Example:
If Laura goes to bed late, she wakes up in a bad mood.
If Lesli meets new people, she is usually quiet and shy.
If i don't do my homework, i'm going to fail.

If i dont clean my room, i can't go out on weekend

If you heat water, it boils or When you heat the water, it boils.
