Which statement applies to the second law of thermodynamics? 

A)  Energy conversion results in less dispersed energy. 
B)  Heat is usually given off from energy conversions. 
C)  Energy can be neither created nor destroyed. 
D)  Energy conversion results in higher quality energy.

Second Law

In thermodynamics, it states that the total entropy of an isolated system can never decrease over time, and is often associated with the concept of energy degradation.

Thermodynamics

The branch of physics that deals with the relationships between heat and other forms of energy, and how these affect matter, encompassing laws that describe energy conservation and entropy.

Energy Conversion

The process of transforming energy from one form into another, such as converting kinetic energy into electrical energy.
