*You can’t tell the materials apart (soda, air, water, ect.)
Physical properties

Physical change
A type of change in which a new substance is NOT formed.
Chemical properties
-characteristics of a substance that indicates it can change chemically
Chemical change
-a change of one substance into another
Solution
A homogenous mixture of particles so small they cannot be seen with a microscope and do not settle
Suspension
A heterogeneous mixture in which visible particles settle.
Colloid
A type of mixture with particles that are larger but still do not settle.
Adhesion
Adhesion causes two different materials to stick together.
Cohesion
-the action of sticking together
Tyndall effect
-light bouncing off the larger particles
Condensation
- the process by which water vapor (water in its gas form) turns into liquid
Evaporation
-when a liquid changes into a gas
