A pressure that will support a column of Hg to a height of 256 mm would support a column of water to what height The density of mercury is 13.6 g/cm³; the density of water is 1.00 g/cm³. A) 1.00 * 10² ft B) 18.8 mm C) 33.8 ft D) 76.0 cm E) 348 cm

Question

Quizplus · Accepted Answer

The height a column of liquid supports is inversely proportional to its density. Given the density of mercury is 13.6 times that of water, a column of water would be 13.6 times taller than a column of mercury for the same pressure. Therefore, $256 \, \text{mm} \times 13.6 = 3481.6 \, \text{mm}$, or 348 cm.
