Question:

Is the releasing of light by a firefly endergonic or exergonic? Explain how such a process abides by the first and second laws of thermodynamics?

Author: fahr dat



Answer:

First law states energy can only be transferred and thus chemical energy is becoming light energy Second law states that in the conversion of energy, the total entropy/disorderness of a closed system increases over time, this is true as the firefly must acquire water and food using muscle energy and afterwards has a chemical reaction, showing that overall more disorder must occur for light to be made also exergonic energy since its being released into the environment
