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.
The Reid vapor pressure (RVP) is frequently used as an indication of volatility of liquid hydrocarbons. The RVP is defined as the absolute pressure (i.e., psia or bar) exerted by a mixture, determined at 100 ÂºF (37.8 ÂºC) and at a vapor to liquid ratio of 4. This is different than the true vapor pressure which is defined as the pressure of a vapor in equilibrium with its condensed phase at a specific temperature. Although the RVP provides a convenient approximation of the absolute vapor pressure of a partly vaporized sample at 100 Â°F, it is not equivalent to the true vapor pressure. In general, RVP is lower than the true vapor pressure due to some small sample vaporization and the presence of water vapor and air in the confined space. The apparatus and procedures for determining the
