The enthalpy energy in condensation process is negative because it releases energy
The entropy in will also decreases .
Temperature affected this change because it will now create free energy if added with this result this is the condestion process
Answer:
c when electrons drop down from a high energy level they emit a photon.
Explanation:
Answer: (C)
The frequency increases as the wavelength decreases
Explanation:
The relation between the frequency and wavelength of a wave is
Frequency = 1 / Wavelength
The Frequency of electromagnetic wave is inversely proportional to the wavelength. So, as the frequency increases, the wavelength of the wave decreases and vise-versa.
The frequency of a wave is number of complete cycles passing a particular point per second. Its S.I unit is Hertz whereas the wavelength of a wave is the distance between two consecutive crest and trough in meters.
So, on increasing the frequency of a wave, there will be more number of the cycles of wave per second which will decrease the distance between the consecutive crest and trough i.e wavelength.
Physical change is where u change physically or on the "outside" hope this helps, have a great day!
