Can you write clearly and understandably, please?

A humidity box for laboratory use is constructed from panes of window glass of thickness 4mm. The temperature inside the box is maintained at 90C and the ambient room temperature is 25C. The heat transfer coefficients at the inner and outer surfaces of the box are, respectively, 20 and 60Wm2K1. (a) Calculate the maximum relative humidity that can be used in the box without condensation occurring on the inner surfaces. (b) To increase the relative humidity, a thin, electrically heated film is attached to the inner surfaces of the box. Calculate the minimum power that must be supplied to the film in order that a relative humidity of 25% can be used without condensation occurring. The saturated vapor pressure of water p (in Pa) varies with temperature (K) as lnp=T66804.65lnT+56.97 6.11 (a) 13.3% (b) 833W/m2
