A lottery machine uses blowing air to keep 2000 Ping-Pong balls bouncing around inside a 1.0 m \times 1.0 m \times 1.0 m box. The diameter of a Ping-Pong ball is 3.0 cm. What is the mean free path between collisions?

Step 1
The volume of the box is given by: Volume = length x width x height Volume = 1.0m x 1.0m x 1.0m Volume = 1.0m^3 Show more…

A lottery machine uses blowing air to keep 2000 Ping-Pong balls bouncing around inside a $1.0 \mathrm{m} \times 1.0 \mathrm{m} \times 1.0 \mathrm{m}$ box. The diameter of a Ping-Pong ball is $3.0 \mathrm{cm} .$ What is the mean free path between collisions? Give your answer in $\mathrm{cm}$.
Calculate the mean free path of Ar at 20°C and 1.00 bar. The collision diameter d = 3.84 x 10^-10 m. In interstellar space, it is estimated that atomic hydrogen exists at a concentration of one particle per cubic meter. If the collision diameter is 2.5 x 10^-10 m, calculate the mean free path. The temperature of interstellar space is 2.7 K.
