Distillation
Distillation Distillation is a common method used to separate liquid mixtures based on differences in their boiling points. When a liquid mixture is heated, the component with the lower boiling point vaporizes first. The vapor is … more

Kinetic Molecular Model of Gases
Characteristics of Gases Unlike solids and liquids, gases have the following unique characteristics: 1. They have no definite shape or volume Gas particles move in all directions and can fill any part of a container. Therefore, … more
Mercury Barometers on Different Planets
What would happen if you brought a mercury barometer to Earth, the Moon, Mercury, Venus, and Mars? Here, we assume that the mercury barometer has a U-shaped tube: one side is open, and the other side … more
Pressure, buoyancy, and gravity applied to a balloon
Assume the pressure inside and outside the balloon is equal at 1 atmosphere. For ease of calculation, the volume and mass of the balloon and string are assumed to be zero. Pressure on a Balloon In … more
Convection in the room: air conditioners and stoves
Convection in the room There are three ways to transfer the heat: conduction, convection, and radiation. Convection is the method by which heat is transferred by the direct movement of particles that make up a liquid … more
Diffusion of ink in cold and hot water
Particle movement according to temperature The matter around us is made up of tiny particles constantly moving. The particles move more actively as the temperature increases. Water particles move more actively in hot water than cold … more
Kinetic Theory Model
Kinetic theory model Gas particles are constantly moving in all directions. However, we cannot observe these gases because they are very small. The “Kinetic theory model” can replace these invisible gas particles with beads and make … more
Vacuum Jar
Vacuum Jar A vacuum jar(or vacuum sealer, vacuum container) is a container that can remove air using a pump. Originally, vacuum jars were made as kitchen utensils to help meat soak in seasoning. Now, they are … more
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. … 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 … 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 … 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 … more
