Question

how many collision per second does each molecule of a gas make, when average speed of the molecules is 500m/s and mean free path is ​

Answer 1

Answer:

here, υ=500m/s and

mean free path, λ=2.66×10−7m

∴ number of collisions made per second by each molecule = collision frequency

=υλ=5002.66×10−7

=1.88×109(persec)

Answer 2

Answer: 1.88* 10^9

Explanation:

here, υ=500m/s and

mean free path, λ=2.66×10−7m

∴ number of collisions made per second by each molecule = collision frequency

=υλ=5002.66×10−7

=1.88×109(persec)
