How to Use the Thermal Properties of Matter PYQ PDF for MHT CET

Start with the 2025 and 2026 papers first, because they hold 5 of the 12 questions.
Use the average-temperature form of Newton's law of cooling for the questions with two cooling intervals.
Learn α, β = 2α and γ = 3α for the expansion questions.
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.
