The enthalpy of vaporization of Substance x is 7.00 kJ/mol and its normal boiling point is -10c . Calculate the vapor pressure of x at -36c. Round your answer to 2 significant digits

At constant pressure p1, the substance goes from solid state to gas as temperature increases   At constant temperature T1, the substance goes from gas state to liquid as pressure increases   The substance exists in the liquid phase by lowering the pressure and the temperature beyond T   At temperature T, the substance coexists in solid, liquid and gas phases   At constant pressure p2, the substance goes from solid state to liquid to gas as temperature increases.
