Phase Transitions: Melting and Boiling

What are Phase Transitions?

Phase transitions describe the transformation of matter from one physical state to another. The three most common phases are solid, liquid, and gas. Each phase exhibits unique properties due to the arrangement and interaction of its atoms or molecules.

Melting and Boiling

Melting is the process by which a solid transitions into a liquid. As heat is applied to a solid, its molecules gain energy and begin to vibrate more vigorously. At a specific temperature known as the melting point, the solid can no longer maintain its rigid structure and melts into a liquid.

Boiling, on the other hand, is the process by which a liquid transforms into a gas. As heat is applied to a liquid, its molecules gain even more energy and start to move faster and further apart. At the boiling point, the liquid vaporizes and forms a gas.

Phase Transitions in Tin(II) Bromide

Tin(II) bromide undergoes phase transitions at specific temperatures.
