Particle Simulation of Thermal Conduction

About this simulation This simulation shows the particle’s temperature by its color.● Red means high temperature.● Blue means low temperature. We apply Hooke’s law between particles.($$f=-kx$$) Thermal Conduction Conduction is a method of transfer of heat that occurs primarily in … more

Conduction

Conduction of Heat If a high-temperature object and a low-temperature object are attached to each other, the high-temperature object’s heat moves to the low heat by molecular motion. Examples of Conduction that can be seen around us Gold, silver, iron, … more

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? 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

The principle of air conditioner and refrigerator

The air conditioner The air conditioner is based on ‘evaporative heat'(a phenomenon that absorbs the surrounding heat when the liquid evaporates). The indoor unit suddenly expands the compressed refrigerant through a narrow hole. Then, the refrigerant evaporates into the gas … more

Heat Capacity

Heat capacity ‘Heat capacity’ is the amount of heat to raise the temperature of an object by 1℃. The heat capacity of an object is the specific heat of the object multiplied by the object’s mass. Since the heat capacity … more

Specific Heat

Specific Heat When you apply the same amount of heat to metal and water of the same mass, the metal temperature change is greater than that of water. This is because the amount of heat required to change the temperature … more
