Answer: higher temperature / more kinetic energy / more space between particles / higher volume.
Step-by-step explanation:
1) One postulate of the kinetic theory is that the average kinetic energy of gas particles is proportional to the absolute temperature of the gas.
That means that the higher temperature, the higher the kinetic energy of the molecules, which is the start of the sequence of the relationship between temperature and volume.
2) Since average kinetic energy is proportional to the square of the speed, KE = [1/2] mass × (speed)², it follows that at higher the kinetic energy the faster the molecules will move.
3) By moving faster, the particles will collide more frequently so they will move away from each other, occupying more space.
4) More space between the molecules, is more volume.
So, the sequence is complete: higher temperature → higher kinetic energy (higher speed) → more space → more volume.
