0.75 L bottle is cleaned, dried, and closed in a room where the air is 24°C and 38% relative humidity (that is, the water vapor in the air is 0.38 of the equilibrium vapor pressure at 24°C). The bottle is brought outside and stored at 0.0°C.
(a) What mass of water condenses inside the bottle?
(b) Would water condense at 10°C?

A plastic bottle is closed outdoors on a cold day when the temperature is -11.0°C and is later brought inside where the temperature is 18.5°C. What is the pressure of the air in the bottle after it reaches room temperature, assuming the air in the bottle was at a pressure of 1.00 atm upon reaching thermal equilibrium with the outdoor temperature? Pa

On a particular summer day, the temperature is 30.0°C and the relative humidity is 77.0% (which means that the partial pressure of water vapor in the ambient air is 77.0% of the equilibrium vapor pressure of water). A sample of this air is placed in a 1.00 L flask, which is then closed and cooled to 5.00'C. A: 30.0°C, the vapor pressure of water is 31.8 mmHg. and at 5.00°C is 6.50 mmHg. What is the mass (in grams) of...

10-kg moist air at the temperature of 24°C, the pressure of 100 kPa, and relative humidity of 90% is enclosed in a cylinder and piston assembly. The enclosed air is cooled down to the temperature of 12°C at a constant pressure process (when piston can move freely). Determine a) at what temperature vapor starts to condense and b) the mass of condensed water during the process using the psychrometric chart.

Problem2 (a) Suppose outside temperature is 55 °F while the temperature inside a building is 72 F. The building is heated but not air conditioned, so the partial pressure of water vapor is the same both inside and outside the building. Finally, suppose the dew point outside is 40°F What is the dew point inside? What are the relative humidities inside and outside the building? (We are most comfortable if relative humidity is between 30% and 50%-This question shows why...

On a particular day the room temperature was 300 C and the dew point was observed to be 200 C, and the relative humidity was 80%. With the aid of an air conditioner if a part of the water vapor was removed, and then the relative humidity was 40% and the temperature was 200 C. Suddenly if the due to a power failure the Air conditioner stops working and the temperature rises to 300 C. If no water vapor could...

The air in a room is at 25 °C and a total pressure of 101.325 kPa . Air contains water vapor with a partial pressure of 1.76 kPa. a. Calculate the air humidity and relative humidity. b. Since you intend to use this air for drying fre sh fruits you plan to heat up the air to 50°C. Once you accomplish that, what would be the new relative humidity of the air if the moisture content is maintained? c. Intuitively...

Liquid water in a closed container at 25 degrees C is in equilibrium with water vapor at a pressure of 0.0313 atmospheres. Consider a puddle on a sidewalk at 25 degrees C. If the relative humidity is 38% (i.e., the H2O(g) partial pressure is 0.012 atmospheres) what is the free energy change for evaporation of water from the puddle?
