a. What is the vapor pressure of water at 60°C?
b. What is water’s temperature when its vapor pressure is 100 mmHg?
c. At what temperature would water boil if the external pressure were 500 mmHg?
d. The atmospheric pressure is 250 mmHg. Is water a liquid or a gas at a temperature of 80°C?- A mountain climber in a camp at 3000 m above sea level decides to make pasta for dinner. The package states
that the pasta should be cooked in boiling water for 10 minutes. How should the climber adjust this cooking
time, if at all? Explain.
