In a perfectly elastic collision of gas particles, no kinetic energy is lost during the collision. This means that the total kinetic energy of the particles before the collision is equal to the total kinetic energy after the collision. As a result, the momentum and speed of the particles are conserved.
What else can I help you with?
The kinetic theory assumes that collisions of gas particles are perfectly elastic. What does this statement mean?
The statement that collisions of gas particles are perfectly elastic means that when gas particles collide, they do not lose any kinetic energy in the process. Instead, the total kinetic energy of the system remains constant before and after the collision. This implies that the particles bounce off each other without any deformation or generation of heat, reflecting the ideal behavior assumed in the kinetic theory of gases.
How does temperature affect mean free path?
Mean free path, the average distance a particle travels between collisions, is inversely related to temperature. As temperature increases, the kinetic energy of particles rises, leading to more frequent collisions and thus a shorter mean free path. Conversely, at lower temperatures, particles move more slowly, resulting in fewer collisions and a longer mean free path. Therefore, higher temperatures generally decrease mean free path, while lower temperatures increase it.
What does collisions mean in gas?
In the context of gases, collisions refer to the interactions between gas molecules or between gas molecules and the walls of the container. These collisions result in changes in the motion and energy of the gas particles, leading to phenomena like pressure and temperature changes. The frequency and intensity of collisions impact the properties and behavior of the gas.
Why a mean free path is a macroscopic property of gas rather then a microscopic one?
The mean free path is considered a macroscopic property of a gas because it represents an average distance that gas molecules travel between collisions, which is determined by the collective behavior of a large number of particles. While individual molecular interactions are microscopic, the mean free path emerges from statistical mechanics, summarizing the overall behavior of a gas in bulk rather than focusing on individual molecules. This property is influenced by factors such as temperature, pressure, and molecular size, which are macroscopic in nature. Thus, it reflects the gas's behavior as a whole rather than the dynamics of single particles.
What kinds of particles does the sun eject into the solar wind?
The Solar Wind. (and photons if you mean the light that the Sun emits).

Why the value of coefficient of restitution of a perfectly plastic impact is 0?
Physicists distinguish between elastic and inelastic (and partially elastic) collisions. If you mean "elastic", the coefficient of restitution is 1. If you mean "inelastic", the coefficient of restitution is 0.Why? Because that's how "elastic" and "inelastic" collisions are DEFINED. If all the kinetic energy is maintained, the coefficient (relative speed after collision, divided by relative speed before the collision) is 1 - i.e., no movement is lost. If it is zero, all the movement energy (relative speed) is lost.
What does a perfectly elastic demand curve mean?
it is the graphic representation of the changes in demand due to the availability of equal important substitude.
Does mean free path depend upon temperature?
Yes, the mean free path of particles changes with temperature. Typically, the mean free path decreases with increasing temperature due to increased collisions between particles.

What is perfectlyinelastic collision?
I'm not sure what you mean by "stronger" A perfectly inelestic collision is an ideal event in which none of the kinetic energy of the colliding bodies id tranferred into them as vibrations of their own molecules, i.e. transformed into heat. In an elastic collision, which always happens in the real world, some, or even all, of the kinetic energy of the two objects will be transformed into heat vibrating their molecules. This means that in an inelastic cillision, the bodies final velocities will add up to less than the total velocities that had before the collision, In the ideal state of an inelastic collision though, the sum of their final velocities must equal the sum of their final velocities.
How does number of particles affect thermal energy?
The thermal energy of a system increases with the number of particles because each particle contributes to the overall kinetic energy of the system. More particles mean more potential for collisions and interactions, leading to higher thermal energy. The relationship is directly proportional.
What does a horizontal supply curve mean?
"implies an elasticity equal to infinity" you have a horizontal straight line, you are right that e will be infinite . It will be perfectly elastic at all the points on the line. Because no change in quantity will be will change the price.
What does a flat line mean in a demand curve?
If a market is faced with a horizontal demand curve, then the demand in that market by consumers is perfectly elastic. More simply, any minuscule change in price causes a huge change in quantity demanded.
Is ideal gas one whose particles take up space?
An ideal gas is a theoritical gas consisting of randomly moving particles.The kinetic theory of ideal gases makes 5 main assumptions:The size of molecules is negligible compared with the mean intermolecular distance (i.e. they are widely spaced molecules).Molecules move with different speeds and in random directions.Standard laws of motion apply.Collisions between molecules are elastic. Translational kinetic energy is not converted into other forms of energy.There are no attractive intermolecular forces between molecules except during collision.
What dous sprung mean?
