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...

Covalent Bonds of Hydrocarbon
2022.12.18 Update: Support for double bonds and triple bonds. Why are the outermost electrons of atoms important? The outermost electrons of an atom are essential indicators of the properties of matter. Period 2 and 3 elements, such as carbon, oxygen,...
Ion Model (Whiteboard)
You can create ionic compounds by dragging and dropping atoms. Ion fragments that are no longer needed can be returned to their original location.
Making Molecular Models (Whiteboard)
You can create molecular structures by dragging the atoms. Atoms that no more needed can be returned to the periodic table.
Boiling Point (Ice or Water, Ethanol)
2022.12.08 Update: Applying the specific heat of water and ethanol 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...
Law of Definite Proportions
Law of Definite Proportions In a reaction where hydrogen gas is burned to produce water, two hydrogen atoms combine with one oxygen atom. Hydrogen gas and oxygen gas always react in a ratio of 2:1 to produce water. In this...
Ionic Bond – NaCl
Ion Atoms are made up of an atomic nucleus and electrons. Electrons far from the atomic nucleus may easily fall off, or electrons from outside may enter. If a neutral atom loses an electron, the amount of (+) charge becomes...
Equilibrium Constants
2●\(\rightleftharpoons\)● Chemical equilibrium In a chemical reaction, chemical equilibrium is the state in which both reactants and products are present in concentrations that have no further tendency to change with time. In an equilibrium state at a constant temperature, the...
Particle Simulation of Thermal Conduction
About this simulation This simulation shows the particle’s temperature by its color.● Red means high temperature.● Blue means low temperature. We apply Hooke’s law between particles.(\(f=-kx\)) Thermal Conduction Conduction is a method of transfer of heat that occurs primarily in...
Conduction
Conduction of Heat If a high-temperature object and a low-temperature object are attached to each other, the high-temperature object’s heat moves to the low heat by molecular motion. Examples of Conduction that can be seen around us Gold, silver, iron,...
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...
Precipitation Reaction
A precipitation reaction is a type of reaction when two solutions react to form an insoluble solid (ionic salt) A lot of ionic compounds dissolve in water and exist as individual ions. But when two ions find each other forming...
