SUMMARY
The change in internal energy during the vaporization of water at 100 degrees Celsius is not constant, despite the temperature remaining the same. The enthalpy of vaporization, quantified as x joules per mole, indicates that energy is required for the phase change from liquid to vapor. This energy, known as latent heat, is essential for understanding the thermodynamic processes involved in vaporization. The misconception that internal energy remains constant during this phase change has been clarified through the discussion.
