For light with a wavelength of 12.5 nm, determine the energy of light in kJ/mol
vovikov84 [41]
Energy is related to Wavelength as,

                                   E  =  h c / λ      --------  (1)
As,
       h  =  6.626 × 10⁻³⁴ Js
       c  =  2.99 × 10⁸ ms⁻¹
       λ  =  12.5 nm = 1.25 × 10⁻⁸ m

Putting values in eq. 1,

             E  =  (6.626 × 10⁻³⁴ Js × 2.99 × 10⁸ ms⁻¹) ÷ 1.25 × 10⁻⁸ m

             E  =  1.585 × 10⁻¹⁷ J

             E  =  1.585 × 10⁻²⁰ kJ × 6.022 × 10²³

             E  =  9544.87 Kj/mol

Which Of The Following Would Represent An Increase In Entropy
bagirrra123 [75]


I would say C. Since the material is getting warmer, the atoms and molecules will start to move fasten and then also create more "messiness" (which is entropy with a less-nice word)
