Which of the following explain Surroundings:

• A quantity of matter or a region in space chosen for study.

• A real or imaginary surface that separates the system and its surroundings. It can be fix or movable.

• A real or imaginary surface that separates the system and its surroundings. It must be fix

• Mass or region outside the system

The following picture shows regarding:

• Energy can’t be created or destroyed but energy can change to another form of energy

• Energy has quality as well as quantity, and actual processes occur in the direction of decreasing quality of energy.

• If two bodies are in thermal equilibrium with a third body, they are in thermal equilibrium with each other

If heat energy flows into the system from surrounding, the value will be:

• Positive

• Negative

• Unknown

• Zero

According to Zeroth Law

• If two bodies are in thermal equilibrium with a third body, they are in thermal equilibrium with each other.

• Energy can be neither created nor destroyed but can only be converted from one form to another.

• Energy has quality as well as quantity, and actual processes occur in the direction of decreasing quality of energy

Which of the following explain system

• A quantity of matter or a region in space chosen for study.

• A real or imaginary surface that separates the system and its surroundings. It can be fix or movable.

• A real or imaginary surface that separates the system and its surroundings. It must be fix

• Mass or region outside the system

"The series of states through which a system passes during a process"

This is definition of:

• State

• Properties

• Cycle

If work energy flows to the surrounding, the value will be

• Positive

• Negative

• Unknown

• Zero
