Closed and Isolated Systems Concepts

The video tutorial explains the concept of systems and their boundaries, focusing on three types: open, closed, and isolated systems. An open system allows the exchange of both matter and energy with its surroundings, exemplified by hot water in a cup. A closed system permits only energy exchange, as seen with a water bottle in sunlight. An isolated system, like a thermos flask, exchanges neither matter nor energy. Each system type is defined by its boundary properties, such as permeable, diathermal, or adiabatic.

What is the primary characteristic of a permeable boundary?

• It allows only energy to pass through.

• It allows both matter and energy to pass through.

• It allows only matter to pass through.

• It does not allow anything to pass through.

In an open system, what is exchanged between the system and its surroundings?

• Both matter and energy

• Only energy

• Only matter

• Neither matter nor energy

Which of the following is an example of an open system?

• A vacuum chamber

• A sealed thermos flask

• A closed water bottle

• A cup of hot water

What type of boundary does a closed system have?

• Permeable

• Adiabatic

• Diathermal

• Impermeable

In a closed system, what remains unchanged?

• Energy

• Temperature

• Matter

• Both matter and energy

Which example best illustrates a closed system?

• A thermos flask

• A cup of hot coffee

• A water bottle left in the sun

• An open jar

What is the defining feature of an isolated system?

• It exchanges only energy with its surroundings.

• It exchanges only matter with its surroundings.

• It exchanges both matter and energy with its surroundings.

• It exchanges neither matter nor energy with its surroundings.

Which type of boundary is associated with an isolated system?

• Permeable

• Adiabatic

• Diathermal

• Conductive

What happens to the temperature of a liquid in an isolated system over time?

• It remains the same.

• It decreases.

• It increases.

• It fluctuates.

Which of the following is an example of an isolated system?

• A glass of water

• A thermos flask

• A cup of tea

• An open window
