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 … more
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 … more
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 … 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 … more
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 … more
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 … more
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 … more
Dissolving Dissolving means that the solute diffuses into the solvent and mixes. It is a common case that salt or sugar is dissolved in water. Solvents are often liquid, mostly water. The Earth’s atmosphere is a … more
The air conditioner The air conditioner is based on ‘evaporative heat'(a phenomenon that absorbs the surrounding heat when the liquid evaporates). The indoor unit suddenly expands the compressed refrigerant through a narrow hole. Then, the refrigerant … more
What is Covalent Bond? The covalent bond is a bond formed by atoms. Each atom creates an electron pair and shares it. Because each other’s electrons are shared in pairs, the number of electrons involved in … more
Looking through the VR device, you can observe the 3-dimensional molecular bonding structure of ice.
