Scalar quantity

STATEMENT - 1 : Distance is a vector quantity and displacement is a scalar quantity. STATEMENT - 2 : A person makes a round - trip journey, finishing where she started. The displacement for the trip is 0 and the distance is some nonzero value. STATEMENT - 3 : A person starts at position A and finishes at position B. The distance for the trip is the length of the segment measured from A to B.

Surface tension of a liquid is a molecular phenomenon of liquids involving the force of cohesion among the liquid molecules. It is a scalar quantity and numerically equal to the surface energy. Numerically, it is proved that the potential energy of a liquid is maximum on the surface. Sparingly soluble salts and surface active substances decrease the surface tension of the liquid, however, the fairly soluble solute increase is independent of surface area but if depends on the intermolecular force and the temperature. Surface tension of a liquid is zero at:

Assertion : A physical quantity can be regarded as a vector, if magnitude as well as direction is associated with it. Reason: : A physical quantity can be regarded as a scalar quantity, if it is associated with magnitude only.

Statement-I : A physical quantity can be regarded as a vector, if magnitude as well as direction is associated with it. Statement-II : A physical quantity can be regarded as a scalar quantity, if it is associated with magnitude only.
