Boyle’s Law 2
Drag the standard weight and place it on top of the piston. You can download graph data. Boyle’s Law Doubling the pressure of a gas reduces the volume of the gas by 1/2, and increasing the pressure of a gas...
Molecules in Motion Simulation
Root-Mean-Square Velocity of Gas Molecules (Vrms)
* The gas molecules in the above simulation are all of the same type, and the color of the molecules is for identification purposes only. Kinetic Molecular Theory of Gases ‘Kinetic Theory of Gases’ is a hypothesis to explain the...
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....
Temperature and Reaction Rate
Heat and molecular motion Every object is made up of atoms or molecules that are small particles that the eye can not see. These particles are constantly moved or oscillated themselves. This is called molecular motion. The higher the molecular...
Pascal’s Principle
Pascal’s Principle Pascal’s principle is as follows. “Suppose a closed tube filled with uncompressed fluid. Then, the pressure of this tube’s inside is the same everywhere.” For example, If you press any part of the tube containing the toothpaste, the...
Status Change of Water
Melting point and heat of fusion When heat is applied to ice (solid), the temperature rises gradually. By the way, while the ice is melting, the temperature does not rise. Temperature is kept constant, and the temperature at this time...
Bernoulli’s Principle
This simulation is programmed so that the average velocity of fluid particles flowing through the pipe is constant. What does it mean that the fluid collides against the inner wall of the tube? If the fluid begins to flow in...
Brownian motion
Brownian movement Botanist Robert Brown, while observing pollen on the water’s surface, He noticed that the pollen was constantly moving in random directions. At that time (1827), Brown believed that these movements were driven by special powers as a living...
