Hint
4.
In terms of the kinetic-molecular theory, why do substances expand when heated?
a.
The particles vibrate less and push other particles away.
b.
The particles on the surface vibrate faster.
c.
The particles vibrate more, causing air pressure to compress the substance.
d.
The particles vibrate more and push other particles away.
Hint
5.
Why is it important to take thermal expansion into account when building bridges?
a.
so the bridge materials don't deteriorate
b.
so the bridge will not move at all
c.
so the bridge materials expand and contract with the changes in weather
d.
so the bridge materials can change state as the weather changes
