Thermal Properties of Matter: NEET questions with solutions

NEET uses this chapter for temperature-scale conversions, linear and volume expansion, thermal stress, calorimetry with latent heat, conduction through rods in series, Wien's and Stefan's laws, and Newton's law of cooling. Marks are lost by converting temperature differences as if they were readings, assuming ice always melts completely, and using °C in T⁴.
