Over its entire lifetime (9 billion years), what is the entropy increase in the Sun? The temperature of the Sun is 5750 K. Compare this to the entropy increase caused by life on Earth over the time life has existed here (3.8 billion years). Life needs 1.43 X 101% W of power to do its thing and the temperature of Earth is 15 C. 20). If (somehow) an astero c collision, what woul
