Consider uJT=(dT/dP)H. (this means the rate of change of Temperature divided by the rate of change of pressure at constant enthalpy)
- At constant enthalpy, if the temperature increases and the pressure increases, would you expect uJT to be a positive or negative value?
- At constant enthalpy, if the temperature increases and the volume increases, would you expect uJT to be a positive or negative value?
We irridate an unknown atomic system, in the gas phase, with monochromatic UV radiation of wavelength 0.605x10^-7m and observe a sharp absorption line. All other absorption lines have higher wavelength.
