Bimetal

Bimetal

Bimetal Bimetal is a combination of two metals with different degrees of thermal expansion, and when the temperature of the bimetal increases, it bends toward the smaller degree of thermal expansion. Such bimetals keep the temperature … more

Convection in the room: air conditioners and stoves

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

Cold and Warm Water

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

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

Boiling point measurement

Boiling Point (Ice or Water, Ethanol)

Boiling point and properties of substances All water boils at 100°C when heated, even if it has a different mass. In this way, the same kind of substance has the same boiling point regardless of quantity. … more

Simple Chemical Bonding Simulation

Simple Chemical Bonding Simulation

All atomic models showed only the electrons in the outermost shell. All chemical bonds are depicted as planar, but in reality, they can have three-dimensional structures. ‘In case of unstable, display in red’ may contain an … more

Movement of Ion

Movement of Ion particles

* You can move ion particles with the mouse. Movement of Ion particles Ions acquire electric charge by gaining or losing valence electrons, depending on the type of atom. Electric forces act between charged substances. A … more

PVnRT, Ideal Gas Law

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
