Solution: the pressure generated by the pressure-limiting valve due to its own gravity energy is: f = g = mg = 0.084kg×10n/kg = 0.84n; the pressure generated by the pressure-limiting valve itself on the air hole is p = f/s = 0.84n/(1.2×10. Air pressure generated by the same pair of pressure cookers: pTotal = p+P0 = 7×10.4pa+10.5pa =1.7×10.5pa According to the figure, the air pressure is 6℃ Then, use this pressure cooker to boil water, The highest water temperature can reach116℃ (+1℃) air pressure/105pa1.01.21.31. 00 102 1 10 1 13 1 15 1 18
