Question
Which of the following factors does NOT affect the pressure exerted by a fluid?*1 pointA . DepthB . Density of the fluidC . Acceleration due to gravityD. Temperature of the fluid
Solution
The factor that does NOT affect the pressure exerted by a fluid is D. Temperature of the fluid.
The pressure exerted by a fluid at any point inside the fluid is determined by three factors: the depth within the fluid, the density of the fluid, and the acceleration due to gravity. These factors make up the equation for fluid pressure: P = ρgh, where P is the pressure, ρ is the fluid density, g is the acceleration due to gravity, and h is the height of the fluid column above the point in question.
Temperature does not appear in this equation, so it does not directly affect the pressure exerted by a fluid. However, temperature can indirectly affect pressure by changing the fluid's density. For example, heating a fluid can cause it to expand, which decreases its density. But this is an indirect effect. In the context of the question, the answer is D. Temperature of the fluid.
