1. The problem statement, all variables and given/known data How long does it take the Sun to melt a block of ice at 0°C with an area of 1.10 m2 and thickness 1.07 cm? Assume that the Sun's rays make an angle of 31.1° with the normal to the area, and that the emissivity of ice is 0.0400. 2. Relevant equations Q/t = IeAcos(theta) 3. The attempt at a solution ok, i've done multiple attempts and am still not getting the correct answer! 1) Q/t = IeAcos(Theta) Q/t = (1000 W/m^2)(0.04)(1.10cos(31.1)) = 37.6 J/s but from this number, I don't understand how to find time, should it be one?? or A*h *ρ *L /t = IeACOSθ t = time for ice to melt = IeCOSθ /h *ρ *L t = (1000 W/m^2)(0.04)(cos(31.1)/(0.0107 m)(917 kg/m^3)(3.33*10^5 J/kg) t= 1.05*10^-5 s but, that doesn't work either. I've been trying this problem all afternoon, please help!!
