A scalar value is a single quantity with magnitude only, without direction. Scalars are used in mathematics and physics to represent measurements such as distance, mass, time, temperature, and energy that do not have associated directional information. Scalars can be added, subtracted, and multiplied as mathematical operations.
The quantities that describes about only magnitude is called SCALAR quantity
Yes, you can add a scalar to a vector by adding the scalar value to each component of the vector.
Yes, you can multiply a vector by a scalar. The scalar will multiply each component of the vector by the same value, resulting in a new vector with each component scaled by that value.
They only have a magnitude , no direction.
Refractive index is a scalar quantity because it describes how light propagates through a medium by bending, or refracting, without considering a specific direction of travel.
acceleration is never a scalar...it describes in what direction is the motion of an object changing, so it can't be a scalar...

scalar means a quantity which has only value,but has no direction.
Yes, you can multiply a vector by a scalar. The scalar will multiply each component of the vector by the same value, resulting in a new vector with each component scaled by that value.
In mathematics and physics, a scalar field associates a scalar value to every point in a space. The scalar may either be a mathematical number, or a physical quantity.
They only have a magnitude , no direction.
A scalar value is a single value that represents a magnitude only, without a direction. Examples include temperature, mass, distance, and time.
Transportation
Refractive index is a scalar quantity because it describes how light propagates through a medium by bending, or refracting, without considering a specific direction of travel.
variable
Air pressure inside a tire is a scalar quantity because it only has a magnitude (a numerical value) and no direction.
