This presentation discusses phase transitions between different states of matter - solid, liquid, and gas. It defines phase transitions as transformations between states of matter through heat transfer, such as condensation (gas to liquid), evaporation (liquid to gas), freezing (liquid to solid), melting (solid to liquid), deposition (gas to solid), and sublimation (solid to gas). It also provides brief definitions and examples of solids, liquids, and gases as different states of matter.

2. PHASE TRANSITION
is the transformation of
a thermodynamic system from
one phase or state of matter to another
one by heat transfer. The term is most
commonly used to describe transitions
between solid,liquid and gaseous states of
matter, and, in rare cases, plasma

3. STATE OF MATTER
Solid
• has a definite shape and volume.
• Examples of solids include ice (solid water), a bar of steel, and dry ice (solid carbon
dioxide).
Liquid
• has a definite volume, but takes the shape of its container.
• Examples of liquids include water and oil.
Gas
• has neither a definite volume nor a definite shape.
• Examples of gases are air, oxygen, and helium.
