Scalars are quantities that have magnitude only; they are independent of direction. Conversely, vectors have both magnitude and direction.
A scalar quantity is any numeric value that has no spatial direction. So let's look at your four tests.

A scalar quantity is a physical quantity that is completely described by its magnitude alone, without any direction. Examples include temperature, speed, and mass. Scalars are typically represented by a single numerical value.
There are two types of quantities in Physics scalar and vector. The square of Scalar quantities are positive numbers. The term Scalar was used to denote size or scale not direction. Scalar numbers have direction referred to the attraction negative or repulsion positive.
For example potential energy is a scalar energy E = -mGM/r the negative sign on this scalar denotes gravitational attraction.
A quantity that describes magnitude only not about the direction is called scalar quantity.
Example Height of man is 5ft only explain magnitude or if we buy sugar we are only concerned about quantity of sugar 2kg ,3kg e.t.c not about the 3kg sugar in west directionπ
Scalar quantities are quantities that have magnitude only; they are independent of direction.
Physical quantity which has only magnitude is called scalar quantity. Examples:
time, mass, work, energy, electric current, power, electric charge, magnetic pole strength
More specifically, a scalar is a measurement of a type where a direction is not relevant. When a direction is relevant, the measurement is called a vector.
A scalar quantity is something that only has magnitude and no direction. Any physical quantity that has both magnitude and direction, such as velocity or force, cannot be a scalar quantity.
No, mass is not a scalar quantity. It is a scalar quantity. Scalars have only magnitude and no direction.
No, mass and energy are not scalars. Mass is a scalar quantity while energy is a scalar quantity.
Pressure is a scalar quantity. It is defined as the force per unit area and only has magnitude, not direction.
No, acceleration is not a scalar quantity. It is a vector quantity because it has both magnitude and direction.
