Which of the following best explains why a ventilator is an open system?
It keeps air sealed within a tube
It continuously takes in air and expels carbon dioxide
It stores oxygen in a fixed space
It does not exchange gases
Describe how a dialysis machine functions as a closed system.
It circulates a cleaning solution without external exchange
It removes waste and releases it into the air
It continuously interacts with the surrounding environment
It does not filter any substances
Why is a hydroponic system considered a closed system?
It does not require water to function
It recirculates water without external exchange
It continuously drains water into the ground
It does not provide nutrients to plants
Which of the following describes how an irrigation system differs from a hydroponic system?
An irrigation system recirculates water
A hydroponic system loses water to the environment
An irrigation system continuously exchanges water with the surroundings
Both are closed systems
Explain why radio transmission is an closed system.
A cellular network operates as a closed system as it only transfers energy in the form of radio waves without exchanging physical matter.
A cellular network operates as a closed system as it continuously sends and receives physical substances between cell towers and mobile devices.
A cellular network operates as a closed system as it relies on external inputs of fuel and water to function properly.
A cellular network operates as a closed system as it allows direct material exchange between users and network infrastructure.
Why is fiber-optic communication a closed system?
Light signals travel in a contained medium without external loss
It sends signals into the air
It does not require cables to function
It continuously exchanges energy with the environment
Which of the following best explains why a battery is a closed system?
It burns fuel to generate power
It releases gases into the environment
It stores and releases energy without exchanging matter
Describe how a coal power plant operates as an open system.
It stores energy without releasing it
It burns fuel and releases heat and gases into the environment
It keeps all energy contained within the plant
It does not use combustion
Which of the following is a key difference between an open and closed energy system?
Open systems store energy permanently
Closed systems allow energy exchange with the environment
Open systems release or receive energy from external sources
Closed systems continuously take in external energy
Explain why a traditional irrigation system is an open system.
It continuously takes in and releases water
It stores water without external exchange
It cycles water internally like a hydroponic system
It does not use water from an external source
Which of the following best describes why a hydroponic system is a closed system?
It continuously exchanges water with the environment
It does not need water to function
It recirculates water in a controlled loop
It releases excess water into the ground
Why is a ventilator used in hospitals considered an open system?
It does not exchange gases with the environment
It continuously takes in air and expels carbon dioxide
It stores oxygen in a closed container
It does not interact with the patient’s lungs
Which of the following systems best represents a closed healthcare system?
A dialysis machine that recirculates cleaning solution
A ventilator that takes in and releases air
An oxygen mask providing fresh air
A blood transfusion from one person to another
Explain why a radio transmission network is an closed system.
It transmits and receives signals from external sources without physical matter loss
It keeps signals contained in a fixed environment
It does not allow information to leave
It prevents any outside interference
Which of the following describes how fiber-optic communication works as a closed system?
It transmits light signals within a controlled medium without physical matter loss
It sends and receives signals through open space
It broadcasts messages like a radio
It allows external factors to interfere with the signal
Why is a battery storage unit considered a closed system?
It releases gases into the air
It stores and releases energy without exchanging matter
It continuously takes in new materials
It generates power by burning fuel
Which energy system functions as an open system?
A battery storage unit
A hydroelectric dam with water circulating internally
A coal power plant that burns fuel and emits gases
A rechargeable lithium battery
Why do some renewable energy systems function as open systems?
They store all energy without any loss
They continuously take in external energy (e.g., solar panels absorbing sunlight)
They do not require inputs to function
They recycle energy within a closed circuit
