Challenge Problems
Push your limits with challenges.
Question 1
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?
💡 Hint: Consider energy conservation and how cyclic processes operate.
Question 2
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?
💡 Hint: Think of segment heat transfer and energy conservation.
