Experiment of buoyant force.

Question

1. write a statement of the relation of the apparent loss weight of a body immersed in water to other weights of the body in experiment. why does an immersed body appear to lose weight? would this same relation exist for liquids other than water. explain.

2. one kilogram of steel and one kilogram of aluminum are submerged in water and their apparent weight is recorded. how do the apparent weight compare( qualitatively)? explain.

Answer 1

1. write a statement of the relation of the apparent loss weight of a body immersed in water to other weights of the body in experiment. why does an immersed body appear to lose weight? would this same relation exist for liquids other than water. explain.

an immersed body appears to lose weight because it experiences a force upward, called upthrust.

2. one kilogram of steel and one kilogram of aluminum are submerged in water and their apparent weight is recorded. how do the apparent weight compare( qualitatively)? explain.

density of plain mild steel

is 7.85g/cm³

density of pure aluminium 2.6995g/cm³

since aluminium has lower density, it has larger volume. as such it experiences a greater upthrust causing its apparent weight to be lower than steel.
