A syringe is filled with air and then capped so none of the air can escape, if the syringe was filled with 10mL of air at 1 atm and then the plunger was depressed to 6.4mL of air, what is the new pressure in the syringe? Assume the temperature remains the same
I worked it out and got 1.6atm but want the for sure answer before I submit

Hello, can someone please help me with this question. Please include all steps to make sure I comprehend the solution. Thank You!! To inhale, we contract our diaphragm and intercostal muscles thus expanding the chest cavity and lowering the internal air pressure below normal so that air flows in through the mouth and the nose to the lungs. Suppose a person’s lungs hold about 1300 mL of air at 1 atm. If she expands the chest cavity by 550 mL...
