30-minute practice mock for Chapter 2 Engineering Thermodynamics (AMeE02): 30 MCQs (18 conceptual, 12 numerical) covering thermodynamics basics (systems, properties, zeroth law, ideal gas, quality and property tables), the first law (non-flow processes, specific heats, steady and unsteady flow), the second law (Kelvin-Planck and Clausius, entropy, Carnot, COP, isentropic efficiency), thermodynamic cycles (Rankine, Brayton, Otto, Diesel, vapour-compression and absorption refrigeration), IC engines (SI and CI, components, four-stroke and two-stroke, performance) and applied thermodynamics (boilers, air compressors, refrigerants, psychrometrics, HVAC). Steam-table values needed are given in the questions.
