Finding highest vapor pressure
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 … WebThe saturated vapour pressure of this liquid at the temperature of the experiment is 130 mmHg. You could convert this into proper SI units (pascals) if you wanted to. 760 mmHg is equivalent to 101325 Pa. A value of 130 mmHg is quite a high vapour pressure if we are talking about room temperature.
