The Zero conditional is used for things that are always true as long as the condition is met.
| IF | Condition | Result | Situation |
|---|---|---|---|
| present simple | present simple | ||
| If | you heat water to 100 degrees celsius, | it boils. | fact- universal |
| present simple | present simple | ||
| If | I drink coffee, | I get a headache. | fact- personal |
In these examples, the result will always occur if the condition is met, so the time is not important.
