By: Morgan Cure
Chemical Properties:
What is a Chemical Property?
A chemical property is a property or behavior of a substance when it undergoes a chemical change or a reaction. Examples of this include heat of combustion, reactivity with water, PH, and electromotive force.
Alessandro Volta was the one who started the concept of electromotive force when he invented the well known battery.
What is a Chemical Change?
A chemical change is a process where one or more substances are altered into one or more new and different substances. Examples include the explosion of fireworks, burning a log, cooking rice, and the tarnishing of silver.
Physical Properties:
What is a Physical Property?
A physical property is any property used to characterize matter and energy and their interactions. Some examples include color, smell, density, and melting and or boiling points.
What is a Physical Change?
A physical change is a usually reversible change in the physical properties of a substance. Some examples include crumpling paper, melting an ice cube, casting silver in a mold, and breaking a glass cup.
What is the Law of Conservation of Mass?
What is it?
The Law of Conservation of Mass, also known as the Principal of Mass/Matter Conservation, states that the mass of an isolated object will remain the same overtime.
Antoine Lavoisier discovered the Law of Conservation, and ultimately shared it with the world.
