Meaning of distribution of speed is constant in kinetic molecular theory
Answers
Using the above logic, we can envisage velocity distribution for the given group of particles by plotting the number of those molecules whose velocity falls into series of narrow chains. The result is in the asymmetric curve, which is known as Maxwell-Boltszmann distribution. The peak of the curve represents the most likely velocity between the collection of gas particles.
Velocity distribution is dependent on the temperature and mass of the particles. As temperatures rise, particles gain more dynamic energy. When we plot it, then we see that the rise in temperature causes the Boltzmann plot to spread, in which the relative is transferred to the maximum right.
Large molecular weight varies the distribution of the velocity because all the particles have the same dynamic energy at the same temperature. Therefore, by the equation KE = 12 MV2 KE = 12 MV2, the degree of high velocity particles will increase because atomic weight is reduced.
Root-mean-square speed
Root-mean-square speed measures the average speed of the particles in a gas, which is defined as vrms = √3RT
According to the Kinetic Molecular Principle, gaseous particles are in constant state of random motion; Different particles continue moving at different speeds, continuous collision and direction change. We use velocity to describe the movement of gas particles, so that both motion and direction are kept in mind.
Although the speed of the gaseous particles is constantly changing, the distribution of the velocities does not change. We can not measure the speed of each individual particle, so we often argue in terms of the average behavior of the particles. There is velocity of signals opposite to the particles running in opposite directions. Since the particles of a gas are at random speed, it is estimated that many people are moving in the opposite direction in one direction, which means that the average velocity for collection of gas particles is equal to zero; Since this value is unusable, the velocities can be determined using the average alternative method.
By squaring the velocities and taking square root, we cross the "directional" component of the velocity and also get the average velocity of the particles. Since the value leaves the direction of particles, so now we refer to the value as the average speed. Root-mean-square speed is a measure of the speed of particles in a gas, which is defined as the class root of the average velocity of molecules in the gas.
It is represented by the equation: vrms = √3RTMvrms = 3RTM, where vrms is the basic-mean-square of velocity, the MM kg is the bead mass of the gas in every sesame, R beard gas is stable, and T is the temperature in Calvin.
