Do gases follow any of these principles all the time?
1. The space between gas molecules is much larger than the molecules themselves.
2. Gas molecules are in constant random motion.
3. The average kinetic energy is determined solely by the temperature.
4. All collisions between gas molecules are perfectly elastic.
5. There are no forces of attraction between gas particles.
The kinetic energy of any molecule is due to their movement.
As the motion of the molecules increases, kinetic energy increases.
Higher is the motion of molecules, greater will be the kinetic energy.
Answer and Explanation:
The kinetic energy of the molecules of gases is temperature-dependent.
Higher is the temperature of gases, more will be the kinetic energy.
Lower is the temperature of gases, lesser will be the kinetic energy.
Therefore option (3) is correct.
