Practice identifying and using zero and first conditionals for real situations and future possibilities
Q1. If you heat water to 100°C, it ___ (boil/boils/will boil)
Zero conditional uses present simple in both clauses for general truths
Q2. If it rains tomorrow, I ___ (stay/will stay/stayed) home
First conditional uses 'will + infinitive' in the result clause for future possibilities
Q3. If you mix blue and yellow, you ___ (get/gets/will get) green
Zero conditional uses present simple for things that are always true
Q4. If I ___ (will finish/finish/finished) work early, I will call you
In first conditional, use present simple in the if-clause, not 'will'
Q5. If plants do not get water, they ___ (die/will die/died)
Zero conditional describes what always happens - use present simple
