Pressure is vector quantity .State true or false.
Pressure is vector quantity .State true or false.
The correct option is B False
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.
For example. one that does not appear to move or flow. While
the gas as a whole does not appear to move, the individual molecules of the
gas, which we cannot see, are in constant random motion. Because we are dealing
with a nearly infinite number of molecules and because the motion of the
individual molecules is random in every direction, we do not detect any motion.
If we enclose the gas within a container, we detect a pressure in the gas from
the molecules colliding with the walls of our container. We can put the walls
of our container anywhere inside the gas, and the force per area (the pressure) is the same. We can shrink the size of
our "container" down to an infinitely small point, and the pressure
has a single value at that point.
Therefore, it is false.
