... CQ In Fig. 12.20, the plunger of a syringe is pushed in quickly, and the small pieces of paper in the syringe catch fire. Explain this phenomenon, using the first law of thermodynamics. (Similarly, in a diesel engine, there are no spark plugs. How can the air–fuel mixture ignite?) see Solutions W ...

... take place in an isolated system which is not allowed to exchange heat with or perform work on the environment. The First Law states that the energy is unchanged under any process in an isolated system. This implies that the energy of an open system can only change by exchange of heat or work with t ...

NOTES on THERMODYNAMICS - University of Utah Physics
... Corollary: All reversible (Carnot) engines have the same universal efficiency η(TH , TC ), since each can be used to run the other one backward. The Thermodynamic Temperature Scale: As shown earlier, it is at least theoretically possible to construct a Carnot engine using an ideal gas (or any other tw ...
