## State of Water

By adjusting the temperature of the thermometer, you can observe the state of the water corresponding to the temperature. State of matter The material around us exists in three states (solid, liquid, gas) depending on temperature. Solids do not change … more

## Gas in Various Condition

This simulation supports multitouch. Nature of gas Since the gas can not be seen or touched, a little imagination is needed to understand the ‘nature of the gas.’ In most everyday life, people often do not perceive air. This makes … more

## State of matter

State of matter The material around us exists in three states (solid, liquid, gas) depending on temperature. Solids do not change shape and volume like ice, trees, and so on. The liquid has the property of flowing like water and … more

## 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

## 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

## 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 the gas, the molecular … 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 a result, the pressure … 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 temperature, pressure, and volume … 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 the past, we thought … 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 vapor. When the gas … 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 to produce fewer molecules. … more
