# Does internal potential energy affects temperature or only kinetic energy?

If I take an extreme case, where a body has only an internal potential energy with zero internal kinetic energy, does this body have a temperature? Another question related to it: if two objects A and B having different temperature: A: having only internal potential energy and B having only internal kinetic energy, can heat flow from A to B ?(temperature of A > B)

• You know these cases aren't really possible? Feb 11, 2016 at 21:50
• yes I know. but I want to see if potential energy affects temperature and if potential energy can cause transfer of heat Feb 11, 2016 at 21:54
• Well, I guess no in both cases. Feb 11, 2016 at 22:06
• I believe you know the simple answer to both of your questions to be no. Though you should realize that heat tends to flow from the object with more kinetic energy to that of lower kinetic energy. So why would you think an object with no kinetic energy would transfer heat? It has none to transfer. Feb 12, 2016 at 0:33
• Ok but in general, internal potential energy does not affect temperature? Feb 12, 2016 at 8:24
