The 12 Best Episodes of The Mary Tyler Moore Show (Not Including âChucklesâ) As an appetizer to tonight's Hot in Cleveland reunion episode, sample these dozen delicious episodes of The Mary Tyler Moore Show. This piece originally ran on September 4, 2013. We're rerunning it in light of Mary Tyler Moore's death. In remembrance of Mary Tyler Moore, TV legend, we're taking a look back at the best episodes of her pioneering comedy series, The Mary Tyler Moore Show.
The vapor pressure of water is the pressure at which water vapor is in thermodynamic equilibrium with its condensed state. At higher pressures water would condense. The water vapor pressure is the partial pressure of water vapor in any gas mixture in equilibrium with solid or liquid water. As for other substances, water vapor pressure is a function of temperature and can be determined with ClausiusâClapeyron relation.
Boiling occurs when the vapor pressure reaches or exceeds the surrounding pressure from the atmosphere or whatever else is in contact with the liquid. At standard atmospheric pressure (1 atmosphere = 0.101325 MPa), water boils at approximately 100 degrees Celsius. That is simply another way of saying that the vapor pressure of water at that temperature is 1 atmosphere. At higher pressures (such as the pressure generated in a pressure cooker), the temperature must be higher before the vapor pressure reaches the surrounding pressure, so water under pressure boils at a higher temperature.
