Investigation of the enthalpy of Vaporization for carbon dioxide gas with fixed Temperature condition

Abstract

Enthalpy of vaporization, which asserts that when heat or enthalpy is applied to any liquid substance at a specific pressure and temperature, the liquid turns into a gaseous form, is a crucial characteristic of any liquid. Thus, a change from one state to another takes place. In this work, the Enthalpy of vaporization study is carried out on CO2 gas to understand the variation in it with a change in pressure at a fixed constant temperature. The work is further extended to multiple temperatures, to understand the effect of pressure and temperature change simultaneously on enthalpy. It was found that the enthalpy is directly proportional to pressure and temperature.
