The relationship between frequency and wavelength for an electromagnetic wave is
where
f is the frequency
is the wavelength
is the speed of light.
For the light in our problem, the frequency is
, so its wavelength is (re-arranging the previous formula)
The terms are both about changing states. Vaporizing is when you heat something up into a vapor; condensation is when you lower a vapors temperature to make it become a liquid state.

Answer:
value of heat is 18 J
2. step by step
formular w=p(volume1-volume2)
w= 1.0×10^5(0.0006-0.0004)
w= 40 J
