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 … more

Covalent Bonds of Hydrocarbon
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, and nitrogen can exist in a very stable state … more
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.
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 … more
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 … more
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 … more
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 … more
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, … 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 hypothesis to explain the … more
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 … more
Ionic Bond
Formation and energy of the ionic bonds Metal atoms have strong properties to lose electrons and become cations. On the contrary, non-metallic atoms have strong properties to obtain electrons and become anions. As these two particles approach each other, electrons … more
Where did the pendulum’s energy go? (The second law of thermodynamics and irreversible phenomena)
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 molecules increase their speed. … more
