SUMMARY

The temperature of boiling or melting water remains constant during phase transitions due to the absorption of latent heat. This energy is utilized for the phase change rather than increasing the temperature of the substance. Specifically, when water transitions from solid to liquid or from liquid to gas, the energy supplied is directed towards overcoming intermolecular forces, maintaining a stable temperature throughout the process.

PREREQUISITES
  • Understanding of latent heat and its role in phase transitions
  • Basic knowledge of thermodynamics
  • Familiarity with the concepts of boiling and melting points
  • Knowledge of intermolecular forces
NEXT STEPS
  • Research the concept of latent heat in detail
  • Explore the laws of thermodynamics and their applications
  • Study the phase diagram of water and its implications
  • Investigate the effects of pressure on boiling and melting points
USEFUL FOR

Students of physics, chemistry enthusiasts, and educators seeking to deepen their understanding of phase transitions and thermodynamic principles.

Why does the temperature of boiling or melting water remain constant?
 
Science news on Phys.org
You mean during the phase transition? Because all additional energy furnished to the system goes to producing the phase transition. A substance requires energy to go from solid to liquid or from liquid to gas. Look up latent heat.
