## Ideal Gas Law Calculator

The ideal gas equation is a formula that expresses the law of the relationship between pressure, volume, number, and temperature of ideal gases. With this simple equation, you can calculate the remaining variables you don’t know. In mathematics, this process … more

## 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

## 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

## Stellar Classification

Surface temperature and color of object When the iron is heated, it is initially dark red, but as the iron’s temperature rises, it gradually takes on a yellowish color. This is because the light emitted by the iron changes as … 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

## 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

## 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. The higher the molecular … more
