Question

Problem 15

Answer 1

Given information

We are given that, if the temperature is increased the buoyant force on an aluminum sphere submerged in water increase, decrease, or remain the same.

Step-by-step explanation

Step 1.

According to the Archimedes principle states that the buoyant force on a submerged body is equal to the weight of the liquid displaced by the body and acts vertically upward through the centroid of the displaced volume.

Thus, the net weight of the submerged body is reduced from its actual weight by an amount that equals the buoyant force.
