Detailed explanation-1: -EXPLANATION: Pressure is a scalar quantity. Hence option 2 is the answer.
Detailed explanation-2: -Therefore, pressure is a scalar quantity, not a vector quantity. It has a magnitude but no direction associated with it. Pressure acts in all directions at a point inside a gas. At the surface of a gas, the pressure force acts perpendicular to the surface.
Detailed explanation-3: -Pressure has an intensity but not a direction. In modern terms, it is a scalar, not a vector.
Detailed explanation-4: -Pressure is a scalar quantity, not a vector quantity. It has a magnitude but no direction associated with it. Pressure acts in all directions at a point inside a gas.
Detailed explanation-5: -Pressure is a scalar quantity because it is the ratio of the component of the force normal to the area and it is independent on the size of the area chosen.
