# Can heat energy be transformed into gravitational potential energy? [closed]

I was wondering it it could be done. I know that Heat is just kinetic energy due to vibration of molecules but is it possible for this transformation of energy?

• You can just use a steam engine which lifts a vehical to the top of the mountain (gravitational potential energy) – Lapmid Jan 26 '17 at 5:02
• @Theasgardian I meant something like attraction force around the body – Suraz Basnet Jan 26 '17 at 5:06
• I have a feeling you will have to explain that :). And heat energy/engines include cars, so you might have to define that a bit, otherwise its a bit broad, IMO. – user140606 Jan 26 '17 at 5:12

The top left entry $T^{00}$ corresponds to the mass used in Newtonian gravity, but note that the stress-energy tensor contains extra entries labelled as momentum, shear stress and pressure. Understanding what these mean is a little involved, but see Intuitive understanding of the elements in the stress-energy tensor for an explanation. For now we can skip the details and note that the momentum, shear stress and pressure entries are all associated with exactly the sort of random motion that is caused by thermal energy.
