Correct answer: A. 22.22%
- A. 22.22%
- B. 23.23%
- C. 25.25%
- D. 30.30%
Explanation
The efficiency of the Carnot engine working between 177°C and 77°C will be 22.22%.Right answer is A.Explanation:T1=177°C + 273=450 KT2=77°C + 273=350 KE=(1-T2/T1) x100E=(1-350/450)x100E={(450-350)/450) x100E=(100/450)x100E=0.2222×100E=22.22%

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
