THERMODYNAMICS OF ISOTHERMAL AND ADIABATIC CHANGES. 



Heat taken in when a Body expands Isothermally Heat to a neighbouring 

 Adiabatic the same by all paths Change in Temperature when a Body 

 undergoes a small Adiabatic Change Adiabatics steeper than Isothermals 

 Specific Heats at Constant Pressure and Constant Volume Their Ratio y 

 equal to the Ratio of the Isentropic and Isothermal Elasticities Experi- 

 mental Determinations of y for Gases Adiabatic Gas Equation Decrease 

 of Temperature Upwards with Convective Equilibrium Internal Energy

 THERMODYNAMICS OF RADIATION. 



General Principle The Pressure of Radiation The Normal Stream of Radia- 

 tion, the Total Stream, and the Energy Density The Pressure on a fully 

 Radiating Surface The Relation between E and 6 in full Radiation, the 

 Fourth Power Law Full Radiation remains full Radiation in any Adiabatic 

 Change Relation between Volume and Temperature in an Adiabatic 

 Change Entropy Application of Doppler's Principle Change of Energy 

 in a given Wave-Length Change of Energy of each Wave- Length in an 

 Adiabatic Expansion of full Radiation Maximum Value of Energy for 

 given Range of Wave-Length Form of the Function expressing the 

 Distribution of Energy in the Spectrum 333-342
