Thermal Properties of Matter
13 lessons 101 min 2 simulations
Everything in this chapter follows heat as it moves and what it does on arrival. It starts with temperature and how thermometers and the Kelvin scale measure it, then looks at what heat does to a body: it expands (with water's odd behaviour near 4 °C and the stress in a clamped rail), warms by an amount set by the specific heat, or changes state at fixed temperature through latent heat. Calorimetry balances heat lost against heat gained. The last part is about how heat travels: conduction through solids, convection in fluids, radiation through empty space (with Wien's and Stefan's laws), and Newton's law for how fast a hot body cools.
What the exam asks
NEET asks for °C–°F–K conversions, α_V = 3α_l and area expansion 2α_l, thermal stress YαΔT, mixture problems using heat lost = heat gained with latent heat included, heating-curve reading (flat parts = latent heat, slope 1/ms), junction temperature and equivalent conductivity of rods in series, Wien's λ_mT = constant, Stefan's T⁴ law with emissivity, and Newton's cooling with average temperature. Marks slip when ice is assumed to melt fully without checking the heat available, when °C is used in T⁴, when water's density is taken as largest at 0 °C, and when lengths in cm are not turned to m in H = KAΔT/L.
