WebThis is because the path that both work and heat take affects the final amount. As such, engineers classify work and heat as path functions. Path functions depend on the route taken. Counter-intuitively, internal energy is a state function even … WebSep 14, 2016 · As an example, mechanical work and heat are process functions because they describe quantitatively the transition between equilibrium states of a thermodynamic system. Path functions depend on the path taken to reach one state from another. Different routes give different quantities. Examples of path functions include work, heat and arc …

Why is heat transfer a path function? – Wise-Answer

WebPath functions depend on the path taken to reach one state from another. Different routes give different quantities. Examples of path functions include work, heat and arc length. In contrast to path functions, state functions are independent of the path taken. Thermodynamic state variables are point functions, differing from path functions.

WebThe path functions depend on the path taken or covered between two (initial and final) states. For example, work and heat. If different paths are chosen to reach from one point to another point, the work done will be different however you reach the same point in each case. So, work is not a state function as we cannot say that a system will ... WebHeat is a path function because when heat transfer is taking place, there is some change in temperature in system as well as in surrounding. Thus, there must be some work done by …
