9.1 Thermodynamic Systems

• What type of thermodynamic system exchanges neither energy nor matter with its surroundings?

  Isolated system
• What type of thermodynamic system exchanges both energy and matter with its surroundings?

  Open system
• Match the type of thermodynamic system with its energy and matter exchange characteristics:

  Isolated ↔️ No energy, no matter

  Closed ↔️ Energy, no matter

  Open ↔️ Energy, matter
• A thermodynamic system is the portion of the universe we isolate for study
• A well-insulated thermos is a good example of an isolated system.


  True
• Isolated systems exchange both energy and matter with their surroundings.

  False
• An isolated system exchanges neither energy nor matter with its surroundings.
• An adiabatic boundary does not allow heat transfer.
• An isolated system exchanges neither energy nor matter with its surroundings.
• What is a thermodynamic system defined as?

  A part of the universe
• Match the system type with its ability to exchange energy and matter:

  Isolated ↔️ No energy, no matter

  Closed ↔️ Yes energy, no matter

  Open ↔️ Yes energy, yes matter
• An adiabatic boundary allows heat transfer.

  False
• Isolated systems have no energy exchange with their surroundings
• Match the system type with its boundary and example:

  Isolated ↔️ Rigid and adiabatic, thermos flask

  Closed ↔️ Diathermal or adiabatic, cylinder with piston

  Open ↔️ May be movable, human body
• What type of boundary allows heat transfer?

  Diathermal
• A vacuum flask approximates an adiabatic boundary.


  True
• What is the primary characteristic of a thermodynamic system?

  Isolated for study
• An isolated system exchanges both energy and matter with its surroundings.

  False
• What does the boundary of a thermodynamic system control?

  Interaction with the environment
• Order the types of thermodynamic systems based on increasing energy exchange.

  1️⃣ Isolated systems

  2️⃣ Closed systems

  3️⃣ Open systems
• Open systems can exchange both energy and matter with their surroundings.


  True
• A sealed container of boiling water is an example of a closed system.
• What is an example of an open system?

  Human body
• Closed systems exchange matter but not energy with their surroundings.

  False
• Order the types of thermodynamic boundaries based on their flexibility:

  1️⃣ Rigid

  2️⃣ Movable
• Match the system type with its exchange characteristics:

  Isolated ↔️ No energy, no matter

  Closed ↔️ Energy, no matter

  Open ↔️ Energy, matter
• There are three main types of thermodynamic systems
• Isolated systems do not exchange energy or matter
• Give an example of a closed thermodynamic system.

  Sealed container of boiling water
• What type of boundary is typical for an isolated system?

  Rigid and adiabatic
