Question Style in MHT CET Heat Transfer PYQs

Every question in this PDF is a single-correct MCQ. Radiation questions form the largest group, and most need Stefan's law or Wien's law.

Question Style	What it Tests
Conduction	Two rods of the same length and radius joined in series or in parallel, and a composite slab with thermal conductivities K and 2K
Wien's displacement law	Two stars radiating maximum energy at 3.9 × 10⁻⁷ m and 5.2 × 10⁻⁷ m, and the ratio of their temperatures
Stefan's law and cooling	A sphere at 600 K losing heat by radiation and the new rate of cooling, and the energy radiated by a black body at 5780 K

How to Use the Heat Transfer PYQ PDF for MHT CET

Start with the 2025 and 2026 papers first, because they hold 48 of the 97 questions.
Learn Q = KAΔT t / l for conduction, P = σAT⁴ for radiation and λ_m T = constant for Wien's law.
For rods in series, add the thermal resistances; for rods in parallel, add the conductances.
Solve year-wise PYQs by timing yourself, as time management is crucial.
Re-attempt only the questions you got wrong, and note which formula or step you missed.
