What is meant by Maxwell's demon? (Select all that apply)

Choose at least one answer.

	a. An illegal connection to the power grid that allows a person to have free energy.
	b. An imaginary demon that sits on top of a partition in a box. When fast molecules are detected, it allows them to go through a trapdoor. When slow molecules are detected, it shuts the door and they cannot go through.
	c. The demon will have created a situation where the fast molecules will be on one side of the chamber, while the slow molecules will be in the other chamber. A situation of disequilibrium will exist, and one can run an engine and extract energy from this system in violation of the entropy law.
	d. A fictional demon that emerges in this dimension to wreak havoc.
