Guided Notes
Key concepts students will learn:
- •
A heating curve, also known as a phase diagram, shows the relationship between temperature and energy for a material.
- •
For water, the melting point is 0 degrees Celsius, and the boiling point is 100 degrees Celsius.
- •
During phase changes, such as melting or boiling, the temperature remains constant as the energy goes into changing the phase of the material.
