maxwell law of molecular velocities

The rms speed of an oxygen molecule in a sample at 300 K is about 480m/s. This does not mean that the speed of each molecule is 480 m/s. Many of the molecules have speed less than 480m/s and many have speed more than 480m/s. Maxwell derived an equation giving the distribution of molecule..

On plotting a fraction of molecules having different speeds against the speeds of the molecules (along x-axis) a curve known as Maxwell's distribution curve is obtained. ..

Every molecule in a gas is in a state of constant straight-line motion. Molecules very frequently collide with one another, and against the sides of the container (Fig. 15.4). It is assumed that the molecules do not lose energy during these collisions. Hence the sum total amount of the kinetic ener..

Suppose a particle P is moving in a circle as shown below. Let O be the centre and OX be the X-axis. The position of the particle may be described by the angle q . Let the particle move to the position q + d q in a time dt. Assume that the particle keeps changing its position. Thus, we can def..

The relation between colligative property and molecular mass of the solute is based on the following assumptions: i) The solution is dilute so that Raoult's law is obeyed. ii) The solute neither undergoes dissociation nor association in solutio..

The relation between colligative property and molecular mass of the solute is based on the following assumptions: i) The solution is dilute so that Raoult's law is obeyed. ii) The solute neither undergoes dissociation nor association in solution. When the molecular mas..

To Determine Molecular Size - A solution of known concentration of oleic acid in alcohol is prepared. Let 1 cm 3 of oleic acid be dissolved in 500 cm 3 of alcohol to get concentration. Let n drops of this solution be poured on a water surface contained in a flat and broad vessel. Oleic ac..

According to Newton's second law of motion, F = ma If a constant force 'F' is applied to a body for a very long interval of time, the velocity of the body will go on increasing due to the acceleration produced in the body. This velocity may become equal to, or even exc..
