Find the temperature at which water boils on a day in the mountains when the barometric pressure is 593 mmHg. (Given: the heat of vaporization of water is 40.79 kJ/mol) A) 41.5^$\circ$C B) 68.1^$\circ$C C) 93.1^$\circ$C D) 97.0^$\circ$C E) 117^$\circ$C

Question

Quizplus · Accepted Answer

The boiling point of water decreases with a decrease in atmospheric pressure. At a lower pressure than 1 atm (760 mmHg), water boils at a temperature lower than 100°C. Since 593 mmHg is significantly lower than 760 mmHg, the boiling point of water would be less than 100°C, making 93.1°C the most plausible answer among the given options.
