Addition Polymerization
Addition Polymerization It is a reaction that forms a polymer compound while a double bond of a monomer forms a new single bond. When the monomers are bonded, no other small molecules are produced other than … more

Vapor Pressure Lowering
Equal volumes of sugar water and distilled water is in the same cup. Which solution will evaporate faster? Vapor pressure lowering of the solution When sugar (non-volatile solute) dissolves in water, a strong attraction acts between … more
Otto Cycle at Gasoline Engines
Heat engine A heat engine is a machine that operates by moving energy from a hot space to a cold space. In this process, the heat engine converts some of the heat energy into mechanical energy. … more
Ion Exchange Resin
Magic to turn hard water into soft water Soap does not dissolve well in hard water. On the other hand, soap is well solved in soft water. This is because hard water contains calcium ions(Ca2+) or … more
Countercurrent exchange of Distillation equipment
In this simulation, The red arrow indicates high temperature, blue indicates low temperature, and purple indicates medium temperature. The temperature values are for your understanding only and may differ from the actual values. The initial temperature … more
Carnot Engines
A heat engine A heat engine is a machine that moves by moving energy from a hot space to a cold space. In this process, the heat engine converts some of the heat energy into mechanical … more
Boyle’s J Tube
Boyle’s J-tube experiment Boyle’s J-tube experiment is an experiment that Boyle did to prove his law. Boyle experimented with pouring mercury into a J-shaped glass tube with one side blocked. At first, the heights of mercury … more
Bernoulli’s Principle
This simulation is programmed so that the average velocity of fluid particles flowing through the pipe is constant. What does it mean that the fluid collides against the inner wall of the tube? If the fluid … more
Activity Series of Metals
The metal atom’s exchange ratio due to the ion’s valence is ignored. Ionization tendency of metal The tendency of metals to lose electrons and become cations is called the ‘ionization tendency.’ The ionization sequence is an … more
Convection
Convection When you boil water in the kettle, even if you heat only the bottom, the whole water becomes evenly hot. This is because water transfers heat while moving directly. In this way, liquid or gaseous … more
Brownian motion
Brownian movement Botanist Robert Brown, while observing pollen on the water’s surface, He noticed that the pollen was constantly moving in random directions. At that time (1827), Brown believed that these movements were driven by special … more
Thermometer
A thermometer is a device used to measure temperature. There are several types of thermometers, depending on how the temperature is measured. Thermal Expansion: Uses the principle that the volume expands with increasing temperature. Mercury thermometer, … more
