SUMMARY
The discussion centers on the Otto Cycle and the relationship between compression and temperature increase during isentropic compression. It is established that during isentropic compression, the volume decreases and pressure increases, leading to a rise in temperature due to the principles of thermodynamics. Specifically, the internal energy of an ideal gas is directly proportional to its temperature, and when no heat is added (Q=0), positive external work (compression) results in an increase in internal energy, thereby raising the temperature. The equation for change in internal energy, ΔU = Q + W, is critical in understanding this phenomenon.
