Write the ajumption of kinetic theory of gas |
Answer» \tAll gases are made up of molecules which are constantly and persistently moving in random directions.\tThe separation between the molecules is much greater than the size of molecules.\tWhen a gas sample is kept in a container, the molecules of the sample do not exert any force on the walls of the container during the collision.\tThe time interval of collision between two molecules, and between a molecule and the wall is considered to be very small.\tAll the collisions between molecules and even between molecules and wall are considered to be elastic.\tAll the molecules in a certain gas sample obey Newton’s laws of motion.\tIf a gas sample is left for a sufficient time, it eventually comes to a steady state. The density of molecules and the distribution of molecules are independent of position, distance and time. | |
