The gas molecules randomly move in all directions and collide with each other and with the wall of the container. If is difficult to determine the speed of an individual molecule but it had become passible to work out the distribution of molecules among different molecular speeds. This is known as Maxwell Boltzmann distribution consider the following graph about Maxwell's distribution of speed at two different temperature T_(1) " and " T_(2) Select the correct statement (s):

Answer»

Most PROBABLE speed increases with increase in temperature
Fraction of total molecules with most probable VELOCITY decreases with increase in temperature
Area under the CURVE increases with increase in the temperature
none of the above
