The NiO-MgO binary phase diagram is shown on right side In the Phase Diagram, the components are: Mg and Ni Mg, Ni, and O MgO and NiO SS and L In the Phase Diagram, the pure MgO melts at: Line 1 Line 2 Point 1 Point 2 In the Phase Diagram, the liquids is: Line 1 Line 2 Point 1 Point 2 In the Phase Diagram, the number of degree of freedom (F) at \"Point 1\" is equal to: 0 1 2 3

Solution

Part 1 (C) Clearly in diagram we can see The diagram is between NiO and MgO with temperature.

Part 2 (d) Point 2 i.e. upper Intersection point of line 1 and 2

Part 3 (a) Line 1

Part 4 (b) One
