A succession of events which bring the system back to its initial condition is called _.
Correct answer: C. Cycle
- A. Oscillation
- B. Vibration
- C. Cycle
- D. Circle
Explanation
In the context of thermodynamics, physics, and engineering, a "cycle" refers to a series of processes or events that brings a system back to its initial state. In a thermodynamic cycle, a system undergoes a sequence of operations or transformations that ultimately returns it to its original condition, completing a closed loop. Cycles are fundamental to the analysis and understanding of various systems, such as heat engines, refrigeration systems, and other mechanical devices, where energy undergoes a series of transformations and the system returns to its starting point.

About First Law of Thermodynamics
The first law relates heat supplied, work done and the change in internal energy through energy conservation. Problems use sign conventions and apply the law to isothermal, adiabatic, isobaric and isochoric processes. Internal energy is a state function, while heat and work depend on the path followed.
