Question

In this system nothing goes in or out that can affect the system. Energy is the only thing to be exchanged but not matter. What type of system is this?

a. Closed System
b. Open-System
c. Isolated System
d. None of the above

Answer 1

The system described is a closed system, which can exchange energy but not matter with its surroundings, unlike an open or isolated system.

Step-by-step explanation:

In the system described, where nothing can enter or leave in terms of matter, but energy can be exchanged with the surroundings, we are referring to a closed system. This differentiates it from an open system, which can exchange both energy and matter with its surroundings, and an isolated system, which can exchange neither energy nor matter. A good example of a closed system is a sealed pouch of food that is heated in boiling water; the food receives thermal energy from the boiling water, but no matter is exchanged between the two.

An isolated system is one in which neither energy nor matter can be exchanged with its surroundings.For example, an insulated thermos containing hot coffee approximates an isolated system because it does not allow heat or matter to transfer into or out of the system. However, over time, the coffee will cool as heat is transferred to the surroundings.An isolated system is different from a closed system, which can exchange energy but not matter with its surroundings, and an open system, which can exchange both energy and matter with its surroundings.
