For a cyclic process q -w
WebSep 18, 2024 · But a process does not constitute a cycle. For a cycle the temperature must return to its original value. This require us to reverse the constant pressure process to transfer the same amount of heat out of the system … WebJun 16, 2024 · Cyclic Process. If a system is said to be reversible, i.e., For a process if the system returns back to its initial state after doing some work then the process is said to be a cyclic process. For the cyclic process ΔU = 0. Now according to the First Law of Thermodynamics ΔQ = ΔW +ΔU, so if ΔU = 0. ∴ ΔQ = ΔW. Isobaric Process

WebAn ideal gas is taken through a cyclic thermodynamic process through four steps. The amount of heat exchanged in the steps are Q 1=+5960 J , Q 2= 5600 J , Q 3= 3000 J , Q 4=+3600 J respectively. The corresponding quantities of internal energy changes are Δ U 1=+3760 J , Δ U 2= 4800 J , Δ U 3= 1800 J and Δ U 4. Find the value of Δ U 4 and work … WebMay 22, 2024 · A process that eventually returns a system to its initial state is called a cyclic process. At the conclusion of a cycle, all the properties have the same value they had at the beginning. For such a process, the final state is the same as the initial state, and so the total internal energy change must be zero.
