Underwater weighing estimates _____.Multiple choice question.body weightbody massbody volume

Break Down the Problem

1. Identify the purpose of underwater weighing in relation to the options provided: body weight, body mass, body volume.
2. Analyze how underwater weighing works and what it measures.

Relevant Concepts

1. Underwater weighing, also known as hydrostatic weighing, is a method used to estimate body composition.
2. It primarily focuses on measuring body volume by comparing the weight of a person in air versus underwater.

Analysis and Detail

1. Body Weight: This is the measure of gravity's effect on an object. Weight is different from mass as it can vary depending on the gravitational force.
2. Body Mass: Refers to the amount of matter in the body, typically measured in kilograms or grams.
3. Body Volume: This is the amount of space an object occupies. Underwater weighing calculates volume by observing the water displaced when a person is submerged.

Verify and Summarize

Underwater weighing is mainly used to estimate body volume, which can then be used to calculate body density and ultimately body fat percentage.

Final Answer

Underwater weighing estimates body volume.
