Anaerobic treatment is a common treatment process in environmental engineering to degrade organic contaminants. During this process, methane (CH4) is produced which is an explosive gas. So, its pressure in the treatment tank has to be maintained below explosion limit. Question: You want to keep the methane pressure in the tank below 400 kPa, so what should be the maximum pressure you measured at point A? Methane Mercury (sg = 13,6) 8 cm 1 cm A 3 cm 11 cm water 4 cm Oil (sg = 0,8)

11.4 If 42.0 kJ of heat is added to a 32.0-g sample of liquid methane under 1 atm of pressure at a temperature of – 170°C, what are the final state and temperature of the methane once the system equilibrates? Assume no heat is lost to the surroundings. The normal boiling point of methane is –161.5°C. The specific heats of liquid and gaseous methane are 3.48 and 2.22 J/g-K, respectively [find more in Section 11.4]. P = 1.00 atm 42.0 kJ 32.0 g CH4 AHvap = 8.20 kJ/mol T = -170 °C
