Thiirane - Wikipedia

WebVapour pressure is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature. The temperature at which the vapour pressure at the surface of a liquid becomes equal to the pressure exerted by the surroundings is called the boiling point of the liquid. Thiirane, more commonly known as ethylene sulfide, is the cyclic chemical compound with the formula C2H4S. It is the smallest sulfur-containing heterocycle and the simplest episulfide. Like many organosulfur compounds, this species has a highly unpleasant odour. Thiirane is also used to describe any derivative of the parent ethylene sulfide. Web4 Aug 2015 · So the total pressure of the gas phase (water + dry air) is 760 torr. 742 torr is dry air and 18 torr is the partial vapor pressure of water. The air/water mixture has 100% humidity which means that it is saturated with water, hence the term saturated vapor pressure. (In other words if the temperature falls then dew would form, meaning that the ... prepackaged snacks for 6 pack
