Question 13. The water boils at (a) 10°C (b) 50°C (c) 75°C (d) 100°C Answer
The normal boiling point of water is 100oC because this is the temperature at which the vapor pressure of water is 760 mmHg, or 1 atm. Under normal conditions, when the pressure of the atmosphere is approximately 760 mmHg, water boils at 100oC.
