I and II only
II only
III and IV only
Correct answer is D
The solubility of a gas decreases with an increase in temperature and a decrease in pressure.
collisions are perfectly elastic
forces of repulsion exist
forces of repulsion and attraction are in equilibrium
collisions are inelastic
Correct answer is A
According to one of the kinetic theories of gases, When collisions occur, the molecules lose no kinetic energy; that is, the collisions are said to be perfectly elastic.

According to the Kinetic Theory an increase in temperature causes the kinetic energy of particles to
decrease
increase
be zero
remain constant
Correct answer is B
According to the kinetic theory of gases, when a substance is heated, the average kinetic energy of its molecules increases and this leads to a rise in temperature.
