A barometer has liquid level 10 cm above the outside level and the gas captured inside has the pressure of 0.5 atm, what is the density of liquid?(a) 0.5 atm-s^2/m^2(b) 1 atm-s^2/m^2(c) 1.5 atm-s^2/m^2(d) 2 atm-s^2/m^2 |

Answer» The correct answer is (a) 0.5 atm-s^2/m^2 To explain I would say: Pressure of gas + Pressure of liquid = atmospheric pressure, => 0.5 atm + d*10*0.1 = 1 atm, => d = 0.5 atm-s^2/m^2. |
