Solution: Use the phase diagram for neon to answer the following questions:Below what pressure value will solid neon sublime?

Solution: Use the phase diagram for neon to answer the following questions:Below what pressure value will solid neon sublime?

Problem

Use the phase diagram for neon to answer the following questions:

A phase diagram for neon. The x-axis is temperature in Kelvin, ranging from 0 to 100 with intervals of 20. The y axis is pressure in atmospheres, ranging from 10 to the negative thee to 10 to the positive three. The line separating the solid and gas starts at (15, 10^-3), runs through (18, 10^-2), (22, 10^-1), and ends at (24, 0.4). The line separating the solid and liquid is vertical starting at (24, 0.4) running through (24, 10^3). The curve separating the gas and liquid starts at (24, 0.4) and runs through (36, 10), ending at (44, 27). There is a vertical line separating the liquid and supercritical fluid starting at (44, 27) and running through (44, 10^3). There is a horizontal line separating the gas from the supercritical fluid starting at (44, 27) and running through (100, 27).

Below what pressure value will solid neon sublime?

Solution
  • Sublimation is the phase transition from solid to gas. Use the phase diagram to determine the pressure where solid turns directly to gas
  • Analyzing the phase diagram, the green line appears to be the boundary of solid and gas phase which means that at any point of that particular line, solid and gas exists at the same time
