Science Simulations
* 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 The material around us … 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 perceive air. This makes … 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 flowing like water and … 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 pressure of a gas … 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 hypothesis to explain the … more
Looking through the VR device, you can observe the 3-dimensional molecular bonding structure of ice.
Charle’s Law Assuming constant pressure, increasing the temperature of the gas will speed up the molecular motion. As the gas often collides with the vessel wall, the volume increases. Conversely, if you lower the temperature of the gas, the molecular … more
Boyle’s Law If you press the piston of a syringe containing a certain number of gas molecules, the gas molecules’ space is reduced. Therefore, the gas molecules collide with the syringe wall more and more. As a result, the pressure … more
The force applied per unit area is called pressure. If the force applied to any two points is the same, the larger the area, the smaller the pressure. Conversely, the smaller the area, the greater the pressure. This is why … more
Charle’s Law Charle’s Law In 1787, French scientist Charle (1746-1823) revealed that increasing the temperature of a gas by 1℃ at constant pressure increases the volume of the gas by 1/273 of the volume at 0℃. This is called Charle’s … more
Avogadro’s Law The Italian scientist Avogadro (1776-1856) introduced the molecules’ concept to explain gases’ reactions. According to his theory, the volume of any gas at the same temperature and pressure is proportional to the molecules’ number. In other words, regardless … more
