If the total power per unit area from the Sun incident on a horizontal leaf is 9.00 × 102 W/m2, and we assume that 70.0% of this energy goes into heating the leaf, what would be the rate of temperature rise of the leaf? The specific heat of the leaf is 3.70 kJ/(kg∙°C), the leaf's area is 5.00 × 10−3 m2 , and its mass is 0.500 g.
