State of matter
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
Gas, Liquid, Solid Simulation
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 … more
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 … more
Structure of Ice – 3D VR
Looking through the VR device, you can observe the 3-dimensional molecular bonding structure of ice.
Charles’s Law
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 … more
Boyle’s Law
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 … more
Graph of Charle’s Law
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℃. … more
Avogadro’s Law
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. … more
Three Phase Equilibrium
All naturally occurring elements CAN exist as a solid, liquid, or gas, and all will have at least one triple point. (except Helium) The triple point is the unique combination of temperature and pressure at which … more
