Question
Explain why
Hydrostatic pressure is a scalar quantity even though pressure is force divided by area.
Hydrostatic pressure is a scalar quantity even though pressure is force divided by area.

Answer
When force is applied on a liquid, the pressure in the liquid is transmitted in all directions. Hence, hydrostatic pressure does not have a fixed direction and it is a scalar physical quantity.
