What is the Law of Conservation of Energy, aka 1st Law of Thermodynamics? Follow up ?: How is this significantly different than the Law of Conservation of Matter? Can you articulate examples of the First Law of Thermodynamics?
200
These reactions absorb energy from the environment, mostly in the form of heat.
What are endothermic reactions? Follow up ?: What are two examples of endothermic reactions? Overall, what kind of energy transformation is happening with endothermic reactions?
200
Releases a ton of energy. Easily stored and transported. It is very abundant in the U.S. VS. It produces a lot of greenhouse gasses and other air and water pollutants. It is increasingly energy intensive to mine. The mining process is harmful to human and ecosystem health.

What is the convention for formatting a data table? Follow up ?: How do you format the data table to include data points for replicates?
300
In a system left to its own devices the amount of entropy will always increase.
What is the Second Law of Thermodynamics? Follow up ?: How is this 2nd Law of Thermodynamics illustrated in an energy pyramid?

What is potential energy? Follow up ?: What is the definition of potential energy?
300
Because it takes the disordered electromagnetic energy from the sun and transforms it into the ordered potential energy of glucose.
