Is it possible to boil water at room temperature, say 30°C? If we touch a flask containing water boiling at this temperature, will it be hot?
Yes, it is possible to boil water at 30
Explanation
1. Boiling point decrease with decreases in pressure.
2. So, if the pressure of the flask containing water is reduced up to value so that boiling point is reduced from 100
to 30
then, the water will start boiling.
3. But since now the temperature at which the water has started boiling is very low, flask will not be hot.
