An ideal gas (which is  is a hypothetical gas that conforms to the laws governing gas behavior) confined to a container with a massless piston at the top. (Figure 2) A massless wire is attached to the piston. When an external pressure of 2.00 atmatm is applied to the wire, the gas compresses from 6.40 to 3.20 LL . When the external pressure is increased to 2.50 atmatm, the gas further compresses from 3.20 to 2.56 LL . In a separate experiment with the same initial conditions, a pressure of 2.50 atmatm was applied to the ideal gas, decreasing its volume from 6.40 to 2.56 LL in one step. If the final temperature was the same for both processes, what is the difference between q� for the two-step process and q� for the one-step process in joules? Express your answer with the appropriate units.

Diatomic Gas

Molecule, is a collection of two or more atoms together (which constitute the smallest observable unit) into a pure material. There are some ways to represent the structure of a molecule. Factor symbols represent atoms in Lewis structures, and dots represent electrons that accompany them. A pair of mutual electrons (covalent bond) may be represented by a single dash. The ball-and-stick model depicts the spatial structure of the atoms better.
