NEET Physics (general) MCQ Question
Which of the following combinations about the properties of fluids and their behavior in various scenarios is correct?
Pressure exists at all points in a fluid; capillary rise occurs due to surface tension; pressure is transmitted undiminished throughout the fluid.
Pressure only acts on the walls of containers; capillary rise is due to gravity alone; pressure is not uniform in a fluid.
Fluid pressure varies with temperature only; capillary action is irrelevant to pressure; pressure increases with depth in a fluid.
Pressure is constant in an open fluid system; surface tension has no effect on fluid behavior; fluids cannot transmit pressure.
Correct Answer
Detailed Explanation
Pressure exists at all points in a fluid, and capillary rise occurs due to surface tension effects, as indicated by the Latin origin of 'capilla', relating to narrow tubes. Moreover, it is stated that pressure is transmitted undiminished throughout the fluid.
