Q1: In triangular co-ordinates, the ternery composition point falls __________ of the triangle.

ANS:B - inside

In triangular coordinates, the ternary composition point falls inside the triangle. Triangular coordinates are often used to represent ternary systems, where three components are involved. In this representation, each component is represented by one of the vertices of the triangle, and the composition of the mixture is represented by a point within the triangle. The vertices of the triangle represent the pure components, and any point inside the triangle represents a mixture containing varying proportions of the three components. Therefore, the ternary composition point, which represents the composition of a mixture, falls inside the triangle, not on the corners or the sides.
