Unit #11 GASES Test Review
Kinetic Molecular Theory - true or false?
Gas particles attract and repel each other strongly.
@F/
Gas particles are much smaller than the distances between them.
At standard temperature, different gases have different amounts of kinetic energy
QF)
Compressibility means that gases can be compressed because they are far apart from each other.
All gas particles move in constant, random motion.
When gas particles collide, no kinetic energy is lost.
