Question

Human body is an example for

• A. Open system
• B. Isolated system
• C. Closed system
• D. Adiabatic system

Answer 1

Answer:

A. Open system

• The human body is considered an open thermodynamic system because it continuously exchanges both matter (such as oxygen, food, water, and waste) and energy (such as heat and mechanical work) with its surrounding environment.
  

  System	Exchange
  Open	Matter + Energy
  Closed	Energy only
  Isolated	Neither matter nor energy
