Science Simulations
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
Boiling point and properties of substances All water boils at 100°C when heated, even if it has a different mass. In this way, the same kind of substance has the same boiling point regardless of quantity. … more
* By adjusting the temperature of the thermometer, you can observe the state of the water corresponding to the temperature. * Depending on the temperature of the water, some water molecules may evaporate. State of matter … 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
* By adjusting the temperature of the thermometer, you can observe the state of the water corresponding to the temperature. * Depending on the temperature of the water, some water molecules may evaporate. State of matter … more
All atomic models showed only the electrons in the outermost shell. All chemical bonds are depicted as planar, but in reality, they can have three-dimensional structures. ‘In case of unstable, display in red’ may contain an … more
* You can move ion particles with the mouse. Movement of Ion particles Ions acquire electric charge by gaining or losing valence electrons, depending on the type of atom. Electric forces act between charged substances. A … 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
Neutralization reaction The reaction of an acid and a base to form water is called a neutralization reaction. When an acid and a base react, hydrogen ions from the acid (H+) and hydroxide ions from the … more
State of matter The material around us exists in three states (solid, liquid, gas) depending on temperature. Solids do not change shape and volume like ice, trees, and so on. The liquid has the property of … more
