Question

water normally boils at 100°C but it is possible to boil at 50°C. which variable would you have to change this?​

Answer 1

Explanation:

The boiling point is the temperature at which the vapor pressure of the liquid equals the pressure at enviornment of liquid and the liquid changes to vapor. A liquid in a vacuum has a lower boiling point than when that liquid is at atmospheric pressure

Answer 2

Answer:

The boiling point is the temperature at which the vapor pressure of the liquid equals the pressure at enviornment of liquid and the liquid changes to vapor. A liquid in a vacuum has a lower boiling point than when that liquid is at atmospheric pressure

Thus if water had a boiling point at temperature of 50°C it would mean that we are living in a planet of lower pressure.

Lower the pressure lower the boiling point.

And hey trust me you don't wanna live there, Because the pressure difference between you and the surrounding would be very high such that your blood & body fluids will start boiling ( because those fluids contain 70% or more water content). You would woose out blood through all your pores and have a nasty death.
