Consider a liquid chemical is contained in an open container. The specific gravity of the liquid chemical is 0.750 and the atmospheric pressure (the pressure at the surface) is 14.696 psi. a) Calculate the pressure (in atm) 1.8m below the surface of the container. Show your solution in detail. (20 marks) b) What will happen to the pressure if the container is tightly sealed? Explain the answer in your own words. (10 marks)
