Question

The table here shows the vapor pressure of water at different temperatures. Use this table to answer the following questions. mmHg 20.0 37.0 Part A You are in a mountain range with atmospheric air pressure of 520 mmHg, and you wish to boil some eggs. What is the approximate boiling point of the water at this air pressure? Express your answer as an integer and include the appropriate units. Hints Value Units Submit My Answers Give Up Part B What will happen if you put some 20 °C water in a vacuum chamber and reduce the pressure to Hints The water will diappear instanty. less than 18 mmHg? The wateril boi The water will catch on fire Submit My Answers Give Up Part C A sealed glass jar has a small amount of water on the bottom. The rest of the volume in the jar is taken up by helium gas at a partial pressure of 526 mmHg, and water vapor. If the total pressure inside the jar is 760. mmHg, what is the temperature of the water? Express your answer to three significant figures and include the appropriate units.

Explanation / Answer

You are supposed to use the clausius clapeyron for the first one but since you have a chart let´s use it, there is a rule that says that for every change in pressure of 28 mmHg the boiling point will increase or decrease by 1 C so

760 - 520 = 240

240 / 28 = 8.5714 C of temperature change

since pressure in going down

Temperature of boiling is 100 - 8.5714 = 91.42 C

B)

If you take water and reduce the pressure beyond its vapor pressure it will convert into steam, answer is water will dissapear instantly.
