Question

Is pressure a vector or scaler quantity, explain

Answer 1

it is a scalar quantity because it have only magnitude not direction

Answer 2

Therefore, pressure is a scalar quantity, not a vector quantity. It has magnitude but no direction sense associated with it. Pressureforce acts in all directions at a point inside a gas. ... A closely related quantity is the stress tensor σ, which relates the vectorforce to the vector area via the linear relation .
