Birds are the only vertebrates to have fused clavicles (collarbone) (the furcula or wishbone) or a keeled sternum or breastbone. The keel of the sternum serves as an attachment site for the muscles used for flight or, similarly, for swimming, in penguins.

A gas has an initial volume of 2.4L at a pressure of 1.5 atm and a temperature 273K. The Pressure of the gas increases to 4.5 at
likoan [24]

Answer:

The answer to your question is  V2 = 0.92 l

Explanation:

Data

Volume 1 = V1 = 2.4 l

Pressure 1 = P1 = 1.5 atm

Temperature 1 = T1 = 273 °C

Volume 2 = V2 = ?

Pressure 2 = 4.5 atm

Temperature 2 = 313 °K

Process

To solve this problem use the Combined gas law

                     P1V1/T1 = P2V2/T2

-Solve for V2

                     V2 = P1V1T2 / T1P2

-Substitution

                     V2 = (1.5 x 2.4 x 313) / (273 x 4.5)

-Simplification

                     V2 = 1126.8 / 1228.5

-Result

                     V2 = 0.92 l
