Question

There are 8.8 liters of gas in a piston at a pressure of 1.75 atmospheres. The temperature remains constant, and the gas is compressed to a volume of 6.2 liters. What is the new pressure, in atmospheres, inside the piston?

Answer 1

The new pressure P2 is 2.48 atmosphere.

Explanation:

Here, the one of the product of pressure and volume is equal to the products of pressure and volume of other.

By using Boyles's law,

               pressure is inversely proportional to volume,

                                         P1 V1 = P2 V2

where P1, V1 represents the first pressure and volume,

           P2, V2 represents the second pressure and volume

                                              P2 = (P1 V1) / V2

                                                    = (1.75 $\times$ 8.8) / 6.2

                                              P2  = 2.48 atmosphere.
