Scalar quantity is:
Scalar quantity is: Correct Answer temperature
CONCEPT:
- Scalar quantities: The physical quantities which have only magnitude and no direction are called scalar quantities or scalars.
- A scalar quantity can be specified by a single number, along with the proper unit.
- Examples: Mass, volume, density, time, temperature, electric current, etc.
- Vector quantities: The physical quantities which have both magnitude and direction and obey the laws of vector addition are called vector quantities or vectors.
- A vector quantity is specified by a number with a unit and its direction.
- Examples Displacement, velocity, force, momentum, etc.
EXPLANATION:
- Scalars are the quantities that are described by a magnitude alone. Example - Speed, Volume, Mass, Temperature.
- Force, acceleration, velocity and are all vector quantities.
So, Temperature is a scalar quantities.
Important Points
- Mass is a property of a physical body. It is generally the amount of matter of an object. Since it only has magnitude and no direction, it is a scalar quantity.
- Whereas the weight of an object is a vector quantity since its product of mass times acceleration due to gravity (W= mg), since the product of a scalar and vector quantity is always a vector.
