Systems and Surroundings

[Nicole Pablico]

What are the three different types of systems and how is matter affected by its surroundings?

The three are open, closed, and isolated. Open exchanges both energy and matter, closed can exchange only energy, and isolated cannot exchange either.

Hi! one way to remember them is like a door. You can open it, allowing energy and matter to come in and out. You can close the door, only letting you "walk around the room" like exchanging energy. Lastly, a door isolated from anything cannot let anything in and thus no exchange in either energy or matter is happening.

Adding onto the two prior replies, I think it's helpful to think about the three different types of systems with examples. An open system would be a simple beaker of water; water can evaporate, and the beaker does not insulate the water. A closed system would be a sealed beaker of water; the beaker still does not insulate the water, but now water must stay in the beaker. An isolated system would be the combustion of glucose in a bomb calorimeter; none of the reactants or products of the reaction can escape the system, and the bomb calorimeter insulates everything, preventing energy transfer too. Hope this helps!

The three different types of systems are open, closed, and isolated. In an open system, matter and energy can be exchanged with the surrounding. In a closed system, only energy can be exchanged with the surroundings. In an isolated system, nothing exchanges with the surroundings.

Hello,

There is an open system; matter and energy can exchange with its surroundings.
- think of a beaker of water that is not insulated, water can evaporate.
There is a closed system; energy can exchange with its surroundings.
- think of a sealed beaker of water that is not insulated, no evaporation can occur but can be turned into heat.
There is an isolated system; nothing exchanges with its surroundings.
- think of a heavily insulated beaker no heat can change like in a combustion of glucose in bomb calorimeter

The three different types of systems include, closed, open, and isolated. A closed system only allows for energy to be exchanged, whereas, in an open system, both energy and matter can be exchanged. In an isolated system, neither energy nor matter can be exchanged. All of this is with respect to the surroundings of the system.
