Figure 4. Interaction between two molecules of propane: (a) simulation of the interactions between two propane molecules; (b) at a low temperature (100 °K), both molecules get closer, while (c) at a high temperature (600 °K), the molecules move away from each other. At high temperatures, the kinetic energy is high and overcomes the VDW interaction
