Match the entries given in column A with the appropriate ones in column \(B\). $$ \begin{array}{lllll} \hline & {\text { Column A }} & {\text { Column B }} \\ \hline \text { A. } & 1 \mathrm{~g} \mathrm{~cm}^{-3} & (\quad) & \text { a. } 1000 \mathrm{~kg} \mathrm{~m}^{-3} \\ \text { B. } & \text { Convection current } & ( \quad ) & \text { b. } \mathrm{cm}^{3} \\ \text { C. } & \text { Volume } & ( \quad ) & \text { c. } \text { Measurement of large distances } \\ \text { D. } & \text { Triangulation method } & (\quad ) & \text { d. } \text { Mass/volume } \\ \text { E. } & \text { Mass } & (\quad ) & \text { e. } \text { Change in density } \\ \text { F. } & \text { Density } & \text { ( ) } & \text { f. } \text { kg } \\\ \hline \end{array} $$

Go through column A and analyze each term to find its matching definition or unit in column B.

1 g cm^-3 refers to density in terms of grams per cubic centimeter. In column B, the corresponding unit of density in SI units (kilograms per cubic meter) is in entry a: A = a (1000 kg m^-3).

Convection current refers to the movement of fluid/air due to the change in density. In column B, the corresponding entry which describes change in density is in entry e: B = e (Change in density).

Volume refers to the amount of space that an object occupies, typically measured in cubic units. In column B, the corresponding unit of volume is in entry b: C = b (cm^3).

The triangulation method is used for measuring large distances, typically in surveying or astronomy. In column B, the definition for this term is in entry c: D = c (Measurement of large distances).

Mass refers to the amount of matter in an object, typically measured in kilograms. In column B, the corresponding unit of mass is in entry f: E = f (kg).

Density is defined as mass per unit volume (mass/volume). In column B, the corresponding definition for this term is in entry d: F = d (Mass/volume). Now, with all matches, the final answer is: $$ \begin{array}{lllll} \hline & {\text { Column A }} & {\text { Column B }} \\\ \hline \text { A. } & 1 \mathrm{~g} \mathrm{~cm}^{-3} & (\mathrm{a}) & \text { a. } 1000 \mathrm{~kg} \mathrm{~m}^{-3} \\\ \text { B. } & \text { Convection current } & ( \mathrm{e} ) & \text { b. } \mathrm{cm}^{3} \\\ \text { C. } & \text { Volume } & ( \mathrm{b} ) & \text { c. } \text { Measurement of large distances } \\\ \text { D. } & \text { Triangulation method } & (\mathrm{c} ) & \text { d. } \text { Mass/volume } \\\ \text { E. } & \text { Mass } & (\mathrm{f} ) & \text { e. } \text { Change in density } \\\ \text { F. } & \text { Density } & \text { (\mathrm{d} ) } & \text { f. } \text { kg } \\\ \hline \end{array} $$
