SUMMARY

Perpetual motion is deemed impossible according to the second law of thermodynamics, which states that energy systems tend to move towards equilibrium. The discussion highlights the misconception surrounding gas molecules in a closed container, emphasizing that while they appear to move perpetually, the system is not truly closed due to the motion of surrounding atoms and molecules. Thus, perpetual motion machines cannot exist as they violate fundamental thermodynamic principles.

PREREQUISITES
  • Understanding of the second law of thermodynamics
  • Basic knowledge of kinetic molecular theory
  • Familiarity with closed and open systems in thermodynamics
  • Concept of energy equilibrium in physical systems
NEXT STEPS
  • Research the implications of the second law of thermodynamics on energy systems
  • Explore kinetic molecular theory and its applications in thermodynamics
  • Study examples of closed vs. open systems in physics
  • Investigate the concept of energy equilibrium and its significance in thermodynamic processes
USEFUL FOR

Students of physics, educators in thermodynamics, and anyone interested in the principles governing energy systems and motion.

According to the second law of thermodynamics, perpetual motion is impossible, right?
But how do gas molecules in a closed container move perpetually?

Its really not a closed system. The containers walls are made of atoms/molecules that are in motion as well and outside the system atoms/molecules are in motion.

According to the second law of thermodynamics perpetual motion machines are impossible.
