Question

Why is critical temperature of h2o greater than nh3?

Answer 1

Gases become more difficult to liquefy as the temperature increases because the kinetic energies of the particles that make up the gas also increase. The critical temperature of a substance is the temperature at and above which vapor of the substance cannot be liquefied, no matter how much pressure is applied.

Answer 2

critical temperature of h2o greater than nh3 because H2O have only two hydrogen bond but NH3 have 3 hydrogen bond but due coolant property shown by water so it's critical temperature is high .
