Where did the droplet's energy go? (The second law of thermodynamics and irreversible phenomena)

Where did the droplet’s energy go? (The second law of thermodynamics and irreversible phenomena)

* In this simulation, the attraction between particles is not considered. Where did the droplet’s energy go? Let’s think about the free fall of a water drop. From a macro perspective, falling water droplets change position over time. In this … more

Where did the pendulum's energy go? (The second law of thermodynamics and irreversible phenomena)

Where did the pendulum’s energy go? (The second law of thermodynamics and irreversible phenomena)

Where did the pendulum’s energy go? A pendulum that vibrates in the air continues to collide with air molecules in the process of vibrating. Air molecules get their energy from the pendulum. In this process, Air molecules increase their speed. … more
