The representation of a one-dimensional velocity distribution function for a gas, as the temperature increases:a) it becomes more flattenedb) the maximum occurs for vi = 0 m/sExplain it.
The velocity distribution function of gas moleculesa) is used to measure their velocity, since the small size of gas molecules means that it cannot be measured in any other wayb) is only used to describe the velocity of particles if their density is very high.c) describes the probability that a gas particle has a velocity in a given interval of velocities
Explain why in the representation of a one-dimensional velocity distribution function for a particular gas, the maximum occurs for vi = 0 m/s.
