WebBecause of this path independence, changes in the state functions are often calculated via paths that are simply convenient/hypothetical rather than real. Nevertheless, there are other important quantities, such as heat and work, that are path dependent. These are often called path functions. Explain the difference between state and path variables WebExpert Answer Ans: correct answer is because enthalpy is path independent prop … View the full answer Transcribed image text: The main reason Hess's Law works is: O because DH is an intensive property. O because heat is a path dependent quantity. O because work is zero at constant pressure.

Non-quasistatic transformations cannot be described in terms of the system's unique temperature and pressure. There are two possible ways to answer. The first is just a restatement of the experimental basis of any principle. cara melihat produk key microsoft office

Webd U = δ w + δ q We write a straight Latin d for U to indicate when the change in a state function, where as the changes in work and heat are path-dependent. This is indicated by the 'crooked' δ. We can represent changes as integrals, but only for U can we say that regardless of path we get Δ U = U 2 − U 1 if we go from state one to state two. WebSubstituting this equation into dU = d ′ Q − P dV then yields the general expression (30) for the path-dependent heat. The path can now be specified in terms of the independent … Webtransferred. Since heat is path dependent, however, we must specify the process, i.e., the path, to find . Two useful processes are constant pressure and constant volume, so we will consider these each in turn. We will call the specific heat at constant pressure , and that at constant volume , or and per unit mass. cara melihat respon google form
