According to kinetic molecular theory, collisions
between gas particles in a sample of an ideal gas
(1) increase the energy content of the gas
sample
(2) produce strong attractive forces between
the gas particles
(3) result in a net loss of energy by the gas
sample
(4) transfer energy between the gas particles
