I've read some articles online saying that the temperature is a measure of average kinetic energy of molecules so as the temperature increases, more molecules will bump into each other. However, I still don't quite understand why we feel hot when more molecules bump into each other. Is high temperature allowing more "conduction" to take place between molecules of my own with that of others(i.e. air)? if that is the case, how do we define the "heat content" for a single molecule since heat is defined to be the total kinetic energy of molecules.. I am just having a hard time grasping the mechanism of heat conduction.
