        Δ T = 0 and Δ U =/= 0
        
        Involves either state or configuration change
      - Latent heat
        
        wtf?
        
        amount of heat required to change state of mass m

        Latent heat of fusion
        
        heat released when change from solid to liquid and vice versa
        
        Latent heat of vaporisation
        
        heat released when change from liquid to gas and vice versa
        
        its more than L of fusion since ther is negligible vol change from solid to liq than liq to gas

        also called infrared radations
      - Properties
        
        Follows law of reflections
        
        Exerts Radiation pressure
        
        Radiation of longer wavelength predominant at lower temp
        
        Max radiation wavelength shifts to shorter as temperature rises, changing color.
        
        Prevost Theory
        
        All objects emit radiations
        
        If two bodies at the same temperature are kept close, they radiate and absorb heat at the same rate, so they are in thermal equilibrium.
