In thermodynamics, the surroundings are defined as:

• The boundary of the system.

• The region outside the system.

• The components within the system.

• The energy within the system.

What is the term for a series of processes that returns a system to its initial state?

• Path

• Equilibrium

• Process

• Cycle

Zeroth law of thermodynamics is:

• Kinetic energy of molecules of a gas is zero

• If two systems are thermal equilibrium third one is also in equilibrium

• Ideal gas does not contain molecules

• Absolute zero temperature cannot be obtained

• SYSTEM

What is the meaning of open system?

• 
  Heat & mass transfer across boundary

• 
  No heat & mass transfer across boundary

• Only heat transfer across boundary

• Only mass transfer across boundary

What is the correct definition of a closed system?

• A system that is completely isolated.

• A system where only mass can transfer.

• A system where both mass and energy can transfer.

• A system where energy can transfer but mass remains constant.

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

• A sealed bottle of water.

• A car radiator.

• A pressure cooker with the lid tightly closed.

• A thermos flask.

According to the Zeroth Law of Thermodynamics, if two bodies are each in thermal equilibrium with a third body, they are:

• Not in equilibrium with each other.

• In thermal equilibrium with each other.

• Isolated systems.

• Closed systems.
