Question

Provide a real-world example for a closed system and an open system.

a) Closed system: Earth's atmosphere; Open system: A boiling kettle
b) Closed system: Sealed jar; Open system: Running faucet
c) Closed system: Sealed thermos; Open system: A car engine
d) Closed system: Refrigerator; Open system: A river

Answer 1

A sealed jar is a real-world example of a closed system since it allows energy but not matter transfer, while a running faucet is an example of an open system where both energy and matter are exchanged.

Step-by-step explanation:

When considering real-world examples of closed systems and open systems, it's essential to understand the criteria for each. In a closed system, energy can be exchanged with the surroundings, but matter cannot. In contrast, an open system can exchange both energy and matter with its surroundings. Therefore, a good example of a closed system is a sealed jar, as it allows the transfer of energy (in the form of heat, for example) but not matter. On the other hand, a running faucet is an excellent example of an open system because it allows both water (matter) and energy to be transferred to its surroundings.
