During boiling, the temperature of the liquid water remains constant at the boiling point (until all the liquid has turned into gas), while the particles have enough energy to overcome intermolecular forces. Therefore, we can conclude that:
- The particles will have the same average kinetic energy and the same temperature during boiling.
This is because, even though individual particles are gaining energy and moving apart to form gas, the overall temperature of the liquid remains constant during the boiling process.
