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
Pressure Volume Diagram
You can drag ‘start’ and ‘endpoint.’ Thermodynamics of Gas The gas changes its temperature while exchanging thermal energy with the outside and sometimes does work outside as it expands or contracts. The process of changing the … more
Chemical Reactions in Gas Phase – Ammonia Synthesis
Ammonia synthesis process Ammonia is a widely used material, such as fertilizers, plastic materials, medicines, and daily necessities. Currently, ammonia is being mass-produced at factories. However, when we did not know how to synthesize ammonia in … more
Chemical Reactions in Gas Phase – Water(Steam) Synthesis
Chemical Reactions in Gas Phase Hydrogen gas and oxygen gas react to produce water vapor. The hydrogen gas and the oxygen gas react at a volume ratio of 2: 1 to generate 2 volumes of water … more
Le Chatelier’s Principle
Pressure and chemical equilibrium transfer According to Le Châtelier, if the pressure is increased, the equilibrium position will move to reduce the pressure. The system can reduce the pressure by reacting in such a way as … 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 … more
Temperature and Reaction Rate
Heat and molecular motion Every object is made up of atoms or molecules that are small particles that the eye can not see. These particles are constantly moved or oscillated themselves. This is called molecular motion. … more
Pascal’s Principle
Pascal’s Principle Pascal’s principle is as follows. “Suppose a closed tube filled with uncompressed fluid. Then, the pressure of this tube’s inside is the same everywhere.” For example, If you press any part of the tube … more
Pressure and Pressing Area
The force applied per unit area is called pressure. If the force applied to any two points is the same, the larger the area, the smaller the pressure. Conversely, the smaller the area, the greater the … more
The Ductility and Malleability of Metal
The ductility and malleability of metal When a force is applied to a metal crystal, the metal atom layer is pushed, and the atomic arrangement changes. But at this time, the free electrons move and maintain … more
Reaction Rate
What will the reactant and product concentration curve look like over time? Click the button to start the synthesis reaction. Reaction rate Reaction rate refers to the degree to which a chemical reaction occurs quickly or … more
