Consider 4.60 L of a gas at 365 mmHg and 20 C . If the container is compressed to 2.60 L and the temperature is increased to 36 C , what is the new pressure, P2, inside the container? Assume no change in the amount of gas inside the cylinder.

Explanation:

The given data is as follows.

       [tex]V_{1}[/tex] = 4.60 L,        [tex]P_{1}[/tex] = 365 mm Hg

       [tex]V_{2}[/tex] = 2.60 L,       [tex]P_{2}[/tex] = ?

       [tex]T_{1}[/tex] = (20 + 273) K = 293 K,      [tex]T_{2}[/tex] = (36 + 273) K = 309 K

Since, number of moles of gas are equal so, according to ideal gas equation:

          [tex]\frac{P_{1}V_{1}}{T_{1}}[/tex] = [tex]\frac{P_{2}V_{2}}{T_{2}}[/tex]

          [tex]\frac{365 mm Hg \times 4.60 L}{293 K}[/tex] = [tex]\frac{P_{2} \times 2.60 L}{309 K}[/tex]

          [tex]P_{2}[/tex] = 681.03 mm Hg

Thus, we can conclude that new pressure [tex]P_{2}[/tex] is 681.03 mm Hg.
