Study the following phase diagram of Substance X. pressure (atm) 24 solid 100 liquid 200 temperature (K) Use this diagram to answer the following questions. a gas 300 Suppose a small sample of pure X is held at -12. °C and 12.0 atm. What will be the state of the sample? Suppose the temperature is held constant at -12. °C but the pressure is decreased by 6 atm. What will happen to the sample? Suppose a small sample of pure X is held at -12. °C and 12.0 atm. What will be the state of the sample? Suppose the temperature is held constant at -12. °C but the pressure is decreased by 6 atm. What will happen to the sample? Suppose, on the other hand, the pressure is held constant at 12.0 atm but the temperature is decreased by 116. °C. What will happen to the sample?

Maps [References] Dry nitrogen gas is bubbled through liquid benzene (C6 H6 ) at 23.0°C. From 140.0 L of the gaseous mixture of nitrogen and benzene, 25.0 g benzene is condensed by passing the mixture through a trap at a temperature where nitrogen is gaseous and the vapor pressure of benzene is negligible. What is the vapor pressure of benzene at 23.0°C? Vapor pressure torr Submit Answer Try Another Version 8 item attempts remaining 11:16 PM 33 F 12/6/2021 earch

Using your knowledge of IMF's, rank the following in order of increasing expected vapor pressure. Make sure to explain your logic and indicate which intermolecular force(s) each is capable of forming. H H 1 H H H C H H H H C H H

According to this phase diagram, the normal boiling point of the substance in degree Celsius is:     100     114     0.118     184

Why does the temperature of a substance stay constant during a phase change such as vaporization? Sketch the heating curve for water to help illustrate your answer.
