Explanation Write the expression for the van der walls equation. V ' = V − n b (I) Here, V ' is the volume of space available, V is the total volume available, n is the number of moles and b is the volume occupied by the molecules per mole. Consider all the molecules present are spherical in shape. Write the expression for the volume occupied by the molecules. b = N o ⋅ 4 3 π ( d 2 ) 3 Rearrange the above expression for the diameter. d = 2 ( 3 b 4 π N o ) 1 / 3 (II) Here, N o is the number of molecules in one mole, d is the diameter of the molecule. Conclusion: Substitute 3.2 × 10 − 5 m 3 / mol for b , 6.022 × 10 22 molecules / mol for N o in equation (II)

Kinetic Theory of Gas

The Kinetic Theory of gases is a classical model of gases, according to which gases are composed of molecules/particles that are in random motion. While undergoing this random motion, kinetic energy in molecules can assume random velocity across all dire…

Car A starts from rest at t = 0 and travels along a straight road with a constant acceleration of 6 ft/s^2 until it reaches a speed of 60ft/s. Afterwards it maintains the speed. Also, when t = 0, car B located 6000 ft down the road is traveling towards A at a constant speed of 80 ft/s. Determine the distance traveled by Car A when they pass each other.Write the solution using pen and draw the graph if needed.
