A long cylinder of cross sectional area A = 0.100cm is closed at the top end and open at the bottom end. The bottom end of the tube is immersed in a liquid with a density of p = 6.0 103 kg. The cylinder is held in place in such a way that there is a bubble of air which contains 2.15 x 10-5moles of gas trapped in the top 5.0cm of the cylinder. The system is at room temperature of 20C. The possible configurations of the cylinder are illustrated below: Scm 8. What is the pressure exerted by the gas? (a) 0.95 10Pa (b) 1.00 105 (c) *** 1.05 10P (d) 1.10 10Pa (e) 1.15 x 10 Pa 9. Given that the atmospheric pressure is 1.01 x 105 Pa, where is the bottom of the bubble of air? (a) 11.3cm below the surface of the liquid (b) *** 6.3cm below the surface of the liquid (c) 1.3cm below the surface of the liquid (d) 1.3cm above the surface of the liquid (e) 6.3cm above the surface of the liquid
