Question

Since volume and pressure are inversely related, we can make assumptions about initial and final states using the data provided. We finding trigger words in the language of the problem. Look for words like "first" initially "or" originally to describe initial states and "result" or What volume would a sample of helium occupy at 6.0 atm if the helium was initially compressed in a 1.0 L tank at 20 atm at constant Organize your data into the table to help analyze the problem. Leave blank any boxes for which you do not have information.

Explanation / Answer

Pressure: Initial conditions = 20 atm, Final conditions = 6 atm

Volume: Initial conditions = 1 L, Final conditions = Unknown (Let us assume it to be V)

Since Temperature is given constant,

PV = constant

=> (PV) initial = (PV) final

=> 20 x 1 = 6 x V

=> V = 10/3 = 3.33 L = Volume (final conditions)
