Decide whether each of these statements is True (T) or False
According to the kinetic model of an ideal gas:
(i) The higher the temperature the larger the mean kinetic energies of the molecules.
(ii) Increasing the volume occupied by the gas, with no change in temperature, results in the number of molecular collisions per second with the walls decreasing.
A) (i) T (ii) T
B) (i) T (ii) F
C) (i) F (ii) T
D) (i) F (ii) F

(i) is true according to the kinetic model of an ideal gas: the temperature is proportional to the average kinetic energy of the particles.
(ii) is also true according to the model: increasing the volume of the container will decrease the frequency of molecular collisions with the walls because the particles have more space to move around in.
