4202.8985 K

Explanation:

Using Wien's displacement law which states that the temperature and the wavelength of the blackbody radiation are inversely proportional.

So,

λmax= b/T

Where,

λmax is the peak of wavelength $6.90\times 10^{-7}\ m$

b is the Wien's displacement constant having value as $2.9\times 10^{-3}\ m K$

T is the Absolute Temperature in Kelvin.s

So,

T = b/λmax = $\frac{2.9\times 10^{-3}}{6.90\times 10^{-7}}$ = 4202.8985 K

Condensation

Explanation:

An exothermic process is one in which heat is lost. Condensation is a change of state from gas to liquid. Thus is loses heat.
