Can you boil water without heat? Why and how does it occur?

Add heat until the temperature reaches the boiling point at the fixed pressure. 2. Reduce pressure (e.g. by vacuuming the container water is in) until the boiling point at that pressure drops below the fixed temperature. So, if you would rather not heat your water, you can lower the pressure around it.
