Archimedes' principle states that the weight of the displaced fluid is proportional to its volume, leading to greater buoyancy in larger volume objects with equal mass. Specific gravity is defined as the ratio of the density of a substance to that of a reference substance, typically water, and is useful for differentiating between similar substances. The document also discusses practical applications like hydrometers for measuring car battery efficiency and balloon angioplasty for heart artery treatments.

- 1. Archemides Principle: By Dr. Robert D. Craig, Ph.D.
- 2. Archemides Principle: • Archemides Principle: • The weight of the displaced fluid is directly proportional to the volume of the displaced fluid (specifically if the surrounding fluid is of uniform density). Thus, among objects with equal masses, the one with greater volume has greater buoyancy.
- 4. . Specific gravity • Archimedes' principle, or the law of upthrust, is: • "a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid."
- 6. How to test battery efficiency?? sulfuric acid become dense over usage
- 8. Vocabulary • Hydrometer measuring the specific gravity of a car battery. Keywords hydrometer, measure, measuring, specific gravity, car, automobile, battery, electrical, aci d, instrument
- 9. blocked heart artery with a balloon • Opening a blocked heart artery with a balloon and then propping it open with a wire-mesh stent has become a near-equal partner with bypass surgery for restoring blood flow to the heart
- 11. Specific gravity • Specific gravity is the ratio of the density (mass of a unit volume) of a substance to the density (mass of the same unit volume) of a reference substance. Apparent specific gravity is the ratio of the weight of a volume of the substance to the weight of an equal volume of the reference substance.
- 12. Specific gravity • The reference substance is nearly always water for liquids or air for gases. Temperature and pressure must be specified for both the sample and the reference
- 13. Specific gravity
- 14. Specific gravity • where is the density of the sample and is the density of water. • The apparent specific gravity is simply the ratio of the weights of equal volumes of sample and water in air:
