1.	1. The density of liquid gallium at 30°C is 6.095 g/mL.Because of its wide liquid range (30 to 2400°C),gallium could be used as a barometer fluid at hightemperature. What height (in cm) of gallium willbe supported on a day when the mercury barometerreads 740 torr? (The density of mercury is 13.6 g/mL).(a) 322(c) 165(b) 285(d) 210
Answer» P = density * g * height 740 torr = 98630 Pa 98630 Pa = 6095 kg/m3 * 9.8 m/s2 * Height (m) Height = 1.65 m

Answer»

P = density * g * height

740 torr = 98630 Pa

98630 Pa = 6095 kg/m3 * 9.8 m/s2 * Height (m)

Height = 1.65 m
