Saturation Vapour Pressure
A 1 m^3 closed container contains air with vapor pressure 10hPa. a dish containing 8 g of liquid water is placed in the container. a thermostat maintains the temperature of the air within the container at 25 degree Celsius at all times. In the following, assume a latent heat of vaporization of 2.4*10^6 J/kg.
Will all the water in the dish eventually evaporate?
If the container holds 1.3 kg of dry air, what are the final specific and relative humidities of the air in the container? what is the dew point?
The solution is to find that whether the whole water in a closed container will evaporate at the given temperature or not, and to find the dew-point.

- Vapour Pressure and mass of water vapor - A room is filled with saturated moist air at 30oC and a total pressure of 100 kPa. If the mass of dry air in the room is 100 kg, the mass of water vapor is:
- Dew point - What is the dew point if the humidity is 48.0 percent on a day when the temperature is 25.0oC?
- Anesthetic vaporization and controlled delivery - In a vaporizer a volatile anesthetic liquid is evaporated into a gas which eventually flows to the patient. A lot of attention is directed toward temperature maintenance in order to assure that the p ...
