Science Simulations
Convection in the room There are three ways to transfer the heat: conduction, convection, and radiation. Convection is the method by which heat is transferred by the direct movement of particles that make up a liquid … more
Particle movement according to temperature The matter around us is made up of tiny particles constantly moving. The particles move more actively as the temperature increases. Water particles move more actively in hot water than cold … more
Kinetic theory model Gas particles are constantly moving in all directions. However, we cannot observe these gases because they are very small. The “Kinetic theory model” can replace these invisible gas particles with beads and make … more
Vacuum Jar A vacuum jar(or vacuum sealer, vacuum container) is a container that can remove air using a pump. Originally, vacuum jars were made as kitchen utensils to help meat soak in seasoning. Now, they are … more
The ideal gas equation is a formula that expresses the law of the relationship between pressure, volume, number, and temperature of ideal gases. With this simple equation, you can calculate the remaining variables you don’t know. … more
This simulation supports multitouch. Nature of gas Since the gas can not be seen or touched, a little imagination is needed to understand the ‘nature of the gas.’ In most everyday life, people often do not … more
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 … more
* 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 … more
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 … more
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. … more
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 … more
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 … more
