 The pressure exerted by a column of liquid is equal to the product of the height of the column ti The pressure exerted by a column of liquid is equal to the product of the height of the column times the gravitational constant times the density of the liquid, P=ghd. How high a column of methanol (d= 0.79 g/mL) would be supported by a pressure that supports a 713 mm column of mercury (d = 13.6 g/mL)? A) 713 mm B) 41 mm C) 1.2 x 104 mm D) 9.7x 103 mm E) 17 mm Read 85 times 2 Replies

 Answer:C) 1.2 x 104 mmExplanation:The pressure exerted by a column of liquid is equal to the product of the height of the column times the gravitational constant times the density of the liquid i.e.P = d g hPressure, P = 713 mm column of mercuryDensity, d = 0.79 g/ml = 790 kg/m³We have to find how high a column of methanol would be supported by a pressure P. Let the height is h. So,g = acceleration due to gravity 9.8 m/s²We know that, 1 mm of mercury = 133.32 Pa 713 mm of mercury = 95058.9 Pah = 12.27 mHence, this is the required solution.
