The Zero Conditional

Conditionals are structures that we use when talking about possible actions and their results. The zero conditional is a form that expresses what always happens if or when a certain action takes place.

We can make a zero conditional sentence with two Present Simple verbs (one in the 'if clause' and one in the 'main clause'):

If + present simple, .... present simple.

This conditional is used when the result will always happen.
For example:

If water reaches 100 degrees, it always boils. It's a fact!

note

The two clauses can come in any order.
In written English, if the conditional clause comes first, you put a comma between it and the main clause.
You don't use a comma if the main clause comes first. 

The 'if' in this conditional can usually be replaced by 'when' without changing the meaning.
For example:
If water reaches 100 degrees, it boils.
When water reaches 100 degrees, it always boils.

Here are some more examples:

• If people eat too much fast food, they get fat.

• If you touch a fire, you get burned.

• People die if they don't eat.

• You get water if you mix hydrogen and oxygen.

• Snakes bite if they are scared.

• If babies are hungry, they cry.

  
  Let's watch the video. This video explains how can we use the zero conditional form in real-life situations.
