Question

Question:3 ) EF represents which phase of iron?
A) O Liquid phase
B) O Solid phase
c) O Gaseous phase
D) O Solid and liquid phase together​

Answer 1

Answer:

b number is the answer of this question

Answer 2

Option (C) is the correct answer

EF represents which phase ofthe  iron Gaseous phase

Explanation:

• A phase diagram is the representation of various phasethatch combines the plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance.
• These diagrams are the indication of the physical states that exist under specific conditions of pressure and temperature
• It helps to provide pressure dependence with the phase-transition temperatures. (melting points, sublimation points, boiling points).
• In the graph at origin temperature and heat, both will be zero when heat is given to the substance
• Then the temperature increases and it follows level A, as more and more heat is given to a  substance its temperature does not increases more
• Because of level, B the change of state of a  substance will occur, like level D shows the change of state.
• Level A will represent the solid phase of the substance and level C liquid phase, level E gaseous phase.
