QUIZ 1. What are the SI units for density? a. Grams per meter cubed b. Kilograms per meter cubed c. Milliliters d. Grams per milliliter Answer: b. The actual SI units for density are kilograms per meter cubed. This is relatively impractical so often grams per milliliter or grams per centimeter cubed are often used because water has a density of one gram per cubic centimeter or one gram per milliliter. 2. What is the relationship between density, mass, and volume of a fluid? a. Density is proportional to the mass and volume. b. Density is inversely proportional to mass and inversely proportional to volume. c. Density is proportional to mass and inversely proportional to volume. d. Density is inversely proportional to mass and proportional to volume. Answer: c. The density of something is its mass divided by its volume so it is directly proportional to the mass and inversely proportional to its volume. 3. What is the way to measure the pressure using a barometer? a. Mm water b. Kilopascals c. Atmospheres d. Mm mercury Answer: d. Both blood pressure and barometric pressure are measured in millimeters of mercury. Barometric pressure equals the atmospheric pressure in the environment; it can also measure the pressure at certain altitudes.
