- A sketch of the phase diagram of water is given below. Which statement describing the broken line, (E to F) and/or the diagram is false? Pressure Temperature B E A F At point E the water is all solid ice. O If heat is added to the ice at point E, the temperature of the ice increases until line AB is reached, then the temperature remains constant until all of the ice is melted into liquid. O If more heat is added upon reaching point F, the temperature will remain constant as the liquid water vaporizes. Another way to vaporize all of the liquid water at point F would be to increase the pressure. O Line AC is the vapor pressure curve, liquid and gas are in equilibrium. O Once all the ice has melted (at the intersection of the broken line and line AB) the temperature of the water increases as heat is added until point F is reached.Use the phase diagram of Substance X below to find the pressure at which the melting point of X is -71. °C pressure (atm) 16 8 solid liquid gas 0- 0 200 400 600 temperature (K) Note: your answer must be within 1 atm of the exact answer to be graded correct. ☐ atm X Gon 13 of 22 > Classify each phase based on whether it describes a solid, liquid, or gas.

- Below is a phase diagram. Label the different parts of a phase diagram using the given word/s.90. Like most substances, bromine exists in one of the three typ- ical phases. Br, has a normal melting point of –7.2°C and a normal boiling point of 59°C. The triple point for Br, is T 7.3°C and 40 torr, and the critical point is 320°C and 100 atm. Using this information, sketch a phase diagram for tom bromine indicating the points described above. Based on your phase diagram, order the three phases from least dense to most dense. What is the stable phase of Br, at room tem- fom perature and 1 atm? Under what temperature conditions can liquid bromine never exist? What phase changes occur as the temperature of a sample of bromine at 0.10 atm is increased from -50°C to 200°C?Ethanol melts at -144°C and boils at 78°C.

Enthalpy of vaporization is greater in magnitude than the enthalpy of melting for all substances. b. Some solids have sufficiently high vapor pressures at room temperature that they can directly sublime from solid to vapor without passing through the liquid phase. c. At the boiling point, the liquid phase coexists in equilibrium with its vapor phase as long as the temperature is held constant and the system is kept closed. d. At the critical temperature, a solid can coexist with its liquid and vapor phase as long as the critical pressure is high enough.
