Question

Take into account the phase diagram for the substance Z and state which statement is false.

Patrri) 4 - 1 zo Z() 0 120 -40 - 40 80 (°C)-



Choose one:
a. If we are at point 4 and lower the temperature to 30 ° C, Z will evaporate
b. If we are at point 2 and then reduce the pressure, more of the evaporates of Z
c. At point 3, Z appears exclusively in gaseous form
d. If we are at point 1 and raise the temperature to -20 ° C, dry evaporation ie Z (s) -> Z (g)
e. At point 2, the substance Z is present in all forms (gas, liquid and solid) and the phases are in balance with each other.

Answer 1

From the phase diagram of Z as given in the question, False statement is:

False statement: If we are at point 4 and lower the temperature to 30 ⁰C, Z will evaporate.

Correctness of the statement is lower the temperature to 30 ⁰C, Z will converted more to liquid form
