3. In which of the following condition the
gas doesn’t behave ideally?
a. Gases behave according to what the gas
laws state
b. Gas kinetic energy is conserved
c. Gas does not conform with kinetic
molecular theory
d. Gas particles are considered to have
intermolecular forces
When the __________ of the
gas particles increases the
____________ of the gas also
increase.
Therefore
the
relationship between these
two variables is __________
proportional.
