Thermodynamics Flashcards

Thermodynamics flashcards are a helpful study tool that contain key information related to the subject of thermodynamics. These flashcards typically include definitions, formulas, and concepts that are important to understand in thermodynamics.

Thermodynamics is a branch of physics that deals with the relationships between heat, energy, and work. It helps us understand how energy is transferred and transformed in various systems, such as engines and refrigerators. Thermodynamics is crucial in many scientific and engineering fields.

quick facts

  • Thermodynamics is the branch of physics that deals with heat, energy, and work.
  • Heat is a form of energy that flows from hot objects to cold objects.
  • The first law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted.
  • The second law of thermodynamics states that heat naturally flows from hot to cold objects, and that entropy (disorder) in a closed system always increases.
  • Thermodynamics is used in many fields, including engineering, chemistry, and biology, to understand how energy and heat flow in systems.
