2 cards from this section. Quick, good the night before a test.
What happens to the internal energy of a system in a cyclic process?
Think about the definition of internal energy and cyclic processes.
What does ΔQ represent in the context of thermodynamics?
Consider what happens to energy moving in or out of a system.
In a cyclic process, what is the change in internal energy?
Remember how state functions work.
True or False: The First Law of Thermodynamics states that energy can be created.
Think about the conservation of energy principle.
In a cyclic process, a heat engine absorbs 1000 J of heat. During the cycle, it does 350 J of work on the surroundings. What is the change in internal energy, and what does this tell you about the nature of cyclic processes?
Consider energy conservation and how cyclic processes operate.
If a particular cyclic process results in 200 J of work output but 300 J of heat input is consumed, what is the energy balance for this cycle?
Think of segment heat transfer and energy conservation.
