Final answer:
An individual's loss of weight in water is directly proportional to the volume and weight of the water displaced by the body.
Step-by-step explanation:
The statement is true.
An individual's loss of weight in water is indeed directly proportional to the volume and weight of the water displaced by the body.
This concept is based on Archimedes' principle, which states that the buoyant force on an object equals the weight of the fluid it displaces.
When an object is immersed in water, it experiences an apparent weight loss equal to the weight of the water displaced.
For example, if a person weighs 70 kg and displaces 0.07 m³ of water, their loss of weight in water would be 70 kg * 9.81 m/s² = 686.7 N, which is equal to the weight of the water displaced.
