1. What happens to the pressure and boiling point when there is an increase in altitude?

Question

2. What happens to the altitude and pressure when the boiling point is lowered?
3. What happens to the altitude and boiling point when the pressure is increased?

Answer 1

1. As one ascends to a higher altitude, the air pressure goes down and the boiling point goes down.
2 and 3 don't make sense to me.
