Thermometry

According to kinetic theory of gas Tk  (KE) molecule In case of linear expansion  Conversion of temperature from one scale to another  Constant volume gas thermometer  Constant pressure Thermometer T =  Platinum resistance Thermometer t =  In case of superficial expansion  In case of volume expansion  Work done W =  Q Where  = mechanical equivalent of heat Specific heat s =  Molar heat capacity C = MS C =  Thermal capacity = mS = Q/T Water equivalent W = (m × s)g Heat of transformation L = Q/m or Latent heat Clasius & clapeyron equation  Principle of calorimetry TL  T  TH Where TL = lower temp. T = temp of mixture TH = higher temp. Law of conduction Q = kA  Diffusivity D =  Wiedemann - Franz law  If two rod's in series H =  If two rods in parallel - H =  For convection  H = convection coefficient A = Area  = temp. difference between object fluid Kirchhoff's law - for perfectly body A = 1 According to skfan's law R  T4 or R =  T4 Net loss of energy by body through radiation P = eA(T4 -T04) Newton law of cooling T4 -T04 = 4 T03 T or K =  Planks law  Wien;s law  Kirchoff's law  Stefan's law  Newton's Law of cooling  Wien's law  Plank's law
