Question

Water could be made to boil lower than its normal boiling point of 100 degrees Celsius at 92 degrees Celsius by?

Answer 1

Water could be made to boil lower than its normal boiling point of 100 degrees Celsius at 92 degrees Celsius by lowering the atmosphere or external  pressure.

The boiling point is the temperature at which the vapor pressure of liquid equals the external or atmosphere pressure.

So, if you decrease the external pressure the temperature needed for the liquid reach the lower external pressure is also lower..


You can accomplish by taking the water to higher levels in the Earth (atmosphere pressure at high altitudes is lower than at sea level) or by creating vaccum.
