Pressure may change with direction & it is a TENSOR not a SCALAR.

Since pressure is calculated as the force acting normally per unit area through out the liquid. That's why direction is not considered. Hence pressure is taken as scalar.

Pressure is the scalar quantity because it has only magnitude not direction. Its SI unit is Pascal.

Pressure is the defined through only magnitude.

When we mention the pressure it has no demand of direction. So it is a scalar quantity?
Aravind said:

Pressure don't have direction.

Accepted pressure all are vector quantity therefore pressure is scalar.

Well you don't need to worry if pressure has no direction as long as you know that force, acceleration and velocity have magnitude and direction and as such are vector quantities which makes pressure the odd one out.

Scalar has only magnitude no direction.

As we know from scalar define scalar is a qnty that have only magnitude. Here others have magnitude as well as direction except pressure. Therefore pressure is the correct option.
