Carbon disulfide (CS2) has a vapor pressure of 300 Torr at room temperature (almost half of atmospheric pressure). A sample of CS2 at a temperature of T = 24.8 °C is contained in a vacuum chamber at a pressure of P = 2.50 × 102 Torr in a research lab. If the diameter of the CS2 molecules is d = 2.00 × 10-10 m, estimate the average time between collisions that the gas is experiencing inside the test chamber.
Calculate the magnitude, the direction of resultant force and the coefficient of kinetic friction.
