This simulation explores the relationship between the temperature of a gas, the motion of the particles in the gas and the changes in the kinetic energies of particles during collisions. It is used in Lesson 12 and Lesson 13 of Unit 6.2.

Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other. Examine kinetic energy and speed histograms for light and heavy particles. Explore diffusion and determine how concentration, temperature, mass, and radius affect the rate of …

Gas particles are in constant rapid motion in random directions. The fast motion of gas particles gives them a relatively large amount of kinetic energy. Recall that kinetic energy is the energy that an object possesses because of its motion.

Particles do not influence the flow field of the carrier gas. The first assumption is valid if two conditions are met: (a) particle collisions are infrequent and inconsequential, and (b) particles are not significantly affected when they pass through each others’ wakes.

In a gas, unlike in a solid or a liquid, the particles (atoms or molecules) are relatively far away from each other. The chaotic motion of the gas particles is to be illustrated here in a simulation. Thereby, the model of an ideal gas is taken as a basis. The following assumptions are made:

To learn that the molecules of a gas are in constant random motion. To identify the link between the temperature of a gas and the kinetic energy of the molecules. To understand that when the molecules collide with the wall of their container they exert a force on the wall.

2019年5月4日 · The kinetic theory of gases is a scientific model that explains the physical behavior of a gas as the motion of the molecular particles that compose the gas.

Here we introduce the basic concepts of thermodynamics (TD) necessary to quantify the motion of CF: parameters of the internal state of gas particle, concepts of reversible, irreversible, adiabatic, and isentropic flows.
