Why does evaporation lead to cooling?

This message is often indicative of a data-entry issue and every step should be taken to correct this issue in order to obtain more accurate results. Abstract. The vapour pressure of CO2 has been measured between − 56°C and + 3°C. The results are described by a semi-empirical formula. Special attention has ... must be removed from the wellhead, crude oil, or natural gas condensates so that the liquid product can meet the typical specifications such as vapor pressure ...
