Boyle’s Law - Solutions 1) If I have 5.6 liters of gas in a piston at a pressure of 1.5 atm and compress the gas until its volume is 4.8 L‚ what will the new pressure inside the piston be? P1V1 = P2V2 (1.5 atm)(5.6 L) = (x)(4.8 L) x = 1.8 atm 2) I have added 15 L of air to a balloon at sea level (1.0 atm). If I take the balloon with me to Denver‚ where the air pressure is 0.85 atm‚ what will the new volume of the balloon be? P1V1 = P2V2 (1.0 atm)(15 L) = (0.85 atm)(x) x = 18

First off I have to explain what is the broad practice of chemistry. Chemistry‚ a branch of physical science‚ is the study of the composition‚ properties and behavior of matter. Chemistry is concerned with atoms and their interactions with other atoms‚ and particularly with the properties of chemical bonds. Chemistry is also concerned with
