Define Scaler Quantities with suitable examples.
A scalar quantity is a physical quantity that has only magnitude but does not have a specific direction associated with it. Scalar quantities can be fully described by a single real number or value. Examples include mass, temperature, time, speed, distance, energy, and volume.
