Why joule thomson coefficient for ideal gas is zero?
Asked by ashutosharnold1998 | 08 Aug, 2019, 12:11: AM
answered-by-expert Expert Answer
An ideal gas undergoes neither cooling nor heating on adiabatic expansion in Joule-Thomson experiment hence Joule-Thomson co-efficient for an ideal gas is zero.
 
Explanation:

The intermolecular forces of attraction like Van der Waals forces in an ideal gas are negligible. Hence no energy is used up in overcoming these forces of attraction when the gas expands adiabatically. Thus the internal energy of the gas does not fall and therefore the temperature does not fall.

A vertical hollow cylinder of height 152 cm is fitted with a weightless piston. The lower half is filled with an ideal gas and the upper half with mercury. The cylinder at 300 K is now heated, so that 1 th 4 of the mercury comes out. Find the temperature at which it will happen assuming thermal expansion of Hg to be negligible (1) 340 K (3) 328.12 K (2) 330.6 K (4) 322.2 K
