Test: Phase diagrams and Phase Rule - Question 1

______ variable does depend on how much material you have.

Detailed Solution for Test: Phase diagrams and Phase Rule - Question 1
  • An extensive variable is one that changes when the amount of material changes.
  • Examples include mass, volume, and total energy, which all increase with more material.
  • In contrast, intensive variables, like temperature and density, do not depend on the size of the sample.
  • Therefore, the correct answer is that an extensive variable does depend on how much material you have.
Test: Phase diagrams and Phase Rule - Question 2

For a pure gas, the values of F, C, and P are
Where: F: Degree of freedom, C: Number of independent component, P: Number of phases that can exist in the system

Detailed Solution for Test: Phase diagrams and Phase Rule - Question 2

F – C + P = 2, for Pure gas, number of phases = 1, and component = 1, then F = 2.
