Question

At critical point, the enthalpy of vaporisation is

Answer 1

The heat of vaporization diminishes with increasing temperature and it vanishes completely at a certain point called the critical temperature ( ). Above the critical temperature, the liquid and vapor phases are indistinguishable, and the substance is called a supercritical fluid.

Answer 2

Hi,

The heat of vaporization diminishes with increasing temperature and it vanishes completely at a certain point called the critical temperature. Above the critical temperature, the liquid and vapor phases are indistinguishable, and the substance is called a supercritical fluid.
