The Zero Conditional is used to talk about situations that are

always true if something happens. They are also used to

talk about general truths..

Here we use a simple present in both clauses.

If you give respect, you get respect.

If you heat ice, it melts.

If I am late, my father takes me to school.

If he comes to town, we have dinner together.

In most cases, it is possible to replace a zero conditional by a time clause using when.

When you heat ice, it melts.

When I am late, my father takes me to school.

When he comes to town, we have dinner together.

When you give respect, you get respect

IF + present simple + Will or may/might

We use the first conditional to talk about something that will happen (the result), if a particular condition (which is likely to happen) is met.

When we use will in the result clause of the first conditional, we are certain that something will happen. It is definite . But we can use may or might instead of will. This means that the consequence is possible, but not definite.
