Melting & solidification
Crystal melting shows a temperature plateau during the phase change.
Thermal phenomenaTemperature, phase changes, and specific heat.

Melting & solidification
Crystal melting: temperature rises, then plateaus at the melting point while latent heat is absorbed, then rises again.
Crystal melting: heat up → plateau (solid–liquid, T constant) → heat up again.
Key formulas
Q=cm\Delta TQ=\lambda m
How to use
- Set melting point, heating power, and melt/freeze mode.
- Watch the T–t plateau and beaker state.
- Track latent-heat progress in the readouts.
Applications
- Melting & solidification: Crystal melting: heat up → plateau (solid–liquid, T constant) → heat up again.
- In class, tune parameters for “Melting & solidification”, then check against the textbook result.
FAQ
Why is temperature constant on the plateau?
Energy goes into the phase change (latent heat), not into raising temperature.
What does MVP mean on this page?
An interactive sketch with formulas and parameters. Polished Ready labs are the full bench experience.
What does the “Melting & solidification” lab practice?
Tune parameters and match readouts to the “Melting & solidification” relations — useful for prep and demos.
Why is temperature steady while boiling?
Added heat goes into vaporization near the boiling point.
