But most macroscopic forces are also entropic, for example the forced exerted by an ideal gas on the walls of the container is an entropic force. | |

Which is again really similar to the Depletion force and Casimir effect for what I could understand in the link, right? (non-native so a couple of things in the link were not clear for me) | |
