An ideal gas is enclosed in a cylinder at pressure of 2 atm and temperature, 300 K . The mean time between two successive collisions is 6 x 10-8 s. If the pressure is doubled and temperature is increased to 500 K, the mean time between two successive collisions will be close to :
0.5 x 10-8 s
2 x 10-7 s
3 x 10-6 s
4 x 10-8 s
