Here you have a little explanation about how to use the zero conditional.

CONDITIONALS

2. The Zero (0) Conditional
– We use the zero conditional when we want to talk about facts or
things that are generally true.
– There are two types of facts:
 Facts that are true for everyone. (Herkes için geçerli olan gerçekler)
e.g. If water reaches 100 °C, it boils.
 Facts that are true for a specific person, group, family, etc.
(Belli bir grup için geçerli olan gerçekler.)
e.g. If I eat peanuts, I get sick.

3. Form of Zero Conditional
– 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.
If you heat ice, it melts.
V1 V1
If clause
(action)
Main clause
(result)

4. Usages of the Zero Conditional
– Usually, the if clause is the first part and the main clause is the second
part of a sentence, but they can written in the opposite as well.
If you touch fire, you get burned.
You get burned if you touch fire.

5. Using when instead of if
If = When
– In zero conditional, we can usually replace if with when if it doesn’t
change the meaning of the sentence.
– Genellikle if (eğer) yerine when kullanabiliriz eğer cümlenin anlamını
değiştirmezse.
If babies are hungry, they cry.
When babies are hungry, they cry.
Babies cry when they are hungry.
Babies cry if they are hungry.
OR

6. If clause If + Subject + verb in the present simple
Main clause Subject + verb in the present simple
If you heat water, it boils.
If clause Main clause
Conditional Zero
Water boils if you heat it
Main clause If clause
You can also start
with the main clause
followed by the if
clause.
USE: We use conditional zero for:
 Things that always happen if something happens first.
 Instructions and advice: If you are sick, visit a doctor. If the door is closed, call me.
