Radiant energy from the Sun reaches the Earth at a rate of 1.70 1017 W. When 30.0% of the radiant ...

Radiant energy from the Sun reaches the Earth at a rate of 1.70 × 10¹⁷ W. When 30.0% of the radiant energy is reflected and 70.0% absorbed, the average temperature of the Earth's atmosphere is 253 K or −20 °C. If the atmosphere reflected 20.0% and absorbed 80.0% of the solar radiant energy, then what would be the average temperature of the Earth's atmosphere?
