Hey guys,
Once my teacher was taking class on thermodynamics.. and we came to know about kelvin's experiment.
he said that if the body is cooled upto -273.15 deg. C or 0 kelvin, the pressure exerted by the body will be 0.
I have a doubt.
If p=o,
force/area = 0, mass * g / a = o.
a cannot be infinity.... so there are two cases..
either of mass or acceleration due to gravity is 0
case i.) g=0
that means temp. has efect on gravity... i.e. if temp. =0 , g=0.
as far as iknow gravity and temp. are independent.
case ii.)
m=0
if mass = o, enormous energy will be liberated. And if mass = 0, that means the body no more exists. so how can superconductors exist in 0 deg. kelvin???
and even all tha bodies irrespective of shape and mass should loose all their mass at 0 deg. kelvin which is again practically nt possible...
so please hepl me out..
just tell me how the pressure exerted by the body becomes zero.
