You filled a can of water in the FTTC at 85C and an atmospheric pressure of 101,50 kPa with a fill depth of 1,5 cm (countersink depth diameter of a 1M can is 73 mm. A month later the = 5 mm). The %3! vacuum was 45 kPa. a) Calculate your can's actual headspace volume. b) Calculate the absolute pressure in the headspace. c) Calculate the pressure of air in the headspace at 20C. d) Calculate the mass of air in the headspace at 20C.
