5E. When a mercury-in-glass thermometer is overheated, the top will break off due to the pressure increase from the expansion of mercury which has completed filled the volume of the capillary. A thick, well-tempered glass tube may withstand a maximum pressure of 50 atm without breaking. How far can a thermometer be heated past the temperature at which a capillary is filled before the pressure becomes this large? For mercury, a=1.8x10ª K' and K=3.9x106 atm"'
