Why do bridges have Expansion Joints?
Bridges can slightly expand or contract and the Expansion Joints compensate for this.
What are Phase Changes?
Instances where differences in things like temperature cause something to change from a Solid, a Liquid, or a Gas to something else.
What are the two types of Physical Properties?
Extensive and Intensive.
What are Intensive Physical Properties?
