Question

Assigned as Homework O HQ10.15 Shown below is a representation of the apparatus used by Robert Boyle to determine that gas pressure and volume are inversely related. Why does the addition of mercury to the container increase the pressure inside the J-tube? atmospheric pressure atmospheric pressure Hg added 1 bar extra P Gas Volume 30 mL Volume -60 mL P, /V O A Increased mercury mass heats the trapped air. O B Increased mercury mass cools the trapped air. O Increased mercury mass compresses the trapped air. O D Increased mercury mass expands the trapped air. Unanswered
