Chapter 15, Problem 39P(choose chapter or problem)
Measuring Density with a Hydrometer A hydrometer, a device for measuring fluid density, is constructed as shown in Figure 15–30. If the hydrometer samples fluid 1, the small float inside the tube is submerged to level 1. When fluid 2 is sampled, the float is submerged to level 2. Is the density of fluid 1 greater than, less than, or equal to the density of fluid 2? (This is how mechanics test your antifreeze level. Since antifreeze [ethylene glycol] is more dense than water, the higher the density of coolant in your radiator the more antifreeze protection you have.)
