The following information are given for pure substance Y: - Normal melting point is - 2 °C. - Normal boiling point is 80 °C. - Solid Y sinks in liquid Y at the melting point. - Sublimation can take place at pressures below 0.020 atm. - Critical point is at 140 °C and 53 atm. Which of the following statements is false for Y? Your answer: Vapor pressure of liquid Y at 40 °C is higher than 15.2 mmHg. Temperature at the triple point is less than - 2 °C. O Y at 150 °C and 60 atm is termed supercritical fluid. When Y at 20°C is compressed from 0.010 atm to 2.0 atm, freezing takes place. Boiling point of Y at 900 mmHg is higher than 80 °C.
