Heating of water at atmospheric pressure is an example of an isobaric process. An isobaric process is a thermodynamic process that occurs at constant pressure. In the case of heating water at atmospheric pressure, the pressure remains constant throughout the process, while the temperature of the water increases. The pressure above the open interface is always equal to atmospheric pressure. This is a common scenario in everyday life, such as when you heat water on a stove or in a kettle.
