On a sunny day when the outside temperature is 34.0°C, a car parked in the sun is receiving 812 watts/m2 of incoming solar radiation (Insolation). Because the car radiates heat off of a greater surface area, the car in-turn radiates off heat at a rate of 169 watts/m². If the car is considered a perfect absorber and emitter of radiative energy, what will the equilibrium temperature inside the car be? °C
