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 qqq for the two-step process and qqq for the one-step process in joules?

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
