Question

1. Label the gas phase, the liquid phase, and the solid phase.

2. Label the triple point and define triple point.

3. Define critical pressure.

4. If the temperature remains constant but the pressure is changed, can the phase state be changed? Why or why not?

5. Define the critical point. What happens at the critical point?

6. Define sublimation and deposition.

Explanation / Answer

from left to right; solid->liquid->gas triple point is at 0.5 atm and -10 degree c definition: In thermodynamics, the triple point of a substance is the temperature and pressure at which three phases (for example, gas, liquid, and solid coexist)
