Question
Answer True, False, or Cannot tell to each of the four statements below.
E.g., if the answer to the first statement is `true' and to the rest, `cannot tell', enter TCCCC.
Two cylinders contain liquids. The pressure, P1, at the bottom of cylinder 1 is higher than the pressure, P2, at the bottom of cylinder 2. The ratio, P1/P2, of the absolute pressures is greater than the ratio of the gauge pressures. Water expands when heated (at least above 4 degree C). A beaker of water is heated from 10 degree C to 30 degree C. The pressure at the bottom of the beaker decreases. The absolute pressure at the bottom of a cylinder filled with liquid is Pa=2.0 atm. The liquid is poured into another cylinder having half the radius. The absolute pressure at the bottom of that cylinder is Pa=5.0 atm. Three objects are floating in a fluid, as shown below. The density of object A is largest
