Witryna26 lis 2024 · Because enthalpy is a state function, a process that involves a complete cycle where chemicals undergo reactions and are then reformed back into … Witryna12 kwi 2024 · The enthalpy of water vaporization is the heat required to convert liquid water into gaseous water vapor. The value can be either positive or negative, depending on the direction of the process. If the process is exothermic (releases heat), then the enthalpy is negative; if it is endothermic (absorbs heat), then it is positive.
