Physics: Trivia Questions On The Laws Of Thermodynamics

Thermodynamics is a branch of science which primarily focuses on the relations between heat and various other forms of energy, such as mechanical, chemical or electrical energy, and therefore the relationships between all forms of energy. What do you know about the scientific study?
