Interpretation:
The phase diagram showing given changes in temperature, pressure, and phase is to be identified.
Concept introduction:
A phase diagram is a graph that represents the solid, liquid, and gaseous phases of a substance at different pressures and temperatures.
The x-axis represents temperature change and y-axis represents pressure change.
The lines are the boundary between two phases and represent the conditions under which the two phases are in equilibrium.
Moving from left to right horizontally represents temperature increase and moving from right to left horizontally represents temperature decrease at constant pressure.
Moving downward vertically represents pressure decrease and moving upward vertically represents pressure increase at constant temperatures.

- A pure substance X has the following properties: Mp=90C, increasing slightly as pressure increases; normal bp=120C; liquid vp=65mm Hg at 100C, 20 mm Hg at the triple point. (a) Draw a phase diagram for X. (b) Label solid, liquid, and vapor regions of the diagram. (c) What changes occur if, at a constant pressure of 100 mm Hg, the temperature is raised from 100C to 150C?arrow_forwardKrypton, Kr, has a triple point at 169C and 133 mmHg and a critical point at 63C and 54 atm. The density of the solid is 2.8 g/cm3, and the density of the liquid is 2.4 g/cm3. Sketch a rough phase diagram of krypton. Circle the correct word in each of the following sentences (and explain your answers). a Solid krypton at 130 mmHg (melts, sublimes without melting) when the temperature is raised. b Solid krypton at 760 mmHg (melts, sublimes without melting) when the temperature is raised.arrow_forwardWhat phase changes will take place when water is subjected to varying pressure at a constant temperature of 0.005 C?
