Why intermolecular energy is more in colder objects than in hotter objects?
Asked by Vineeth K | 12 Sep, 2014, 09:02: AM
answered-by-expert Expert Answer
A colder object is more dense than a hotter object. That is, the molecules of a colder object are closer to each other and molecules of hotter object are far from each other.
 
Thus, the intermolecular force (or energy) between the molecules in a colder object is comparatively more than in hotter object.
 
NOTE: A hotter object is at higher temperature, so its molecules will have more kinetic energy. Hence, the net energy of molecules in hotter object is more. This is the reason why energy (heat) is transferred from higher energy to lower energy.

During calculation of acceleration due to gravity above the surface of earth if we assume that there is an external force opposite to that of Earth's gravity then the cos angle will be 180 between the two forces which is negative(-1), if we put the value in the equation of dw = F.dx then the final value of potential energy is positive which is not possible.how and why??

A small spherical object having density 2P is placed inside the liquid of density P and connected to an ideal string of length l whose other end is kept fixed so that the object can move in a vertical cirlcle, minimum speed which must be given at the bottom to just complete the vertical circle.
