Are you a student of physics? How well do you know thermodynamics? Here is a quiz on the isovolumetric process. The isovolumetric process is also known as the isochoric process, constant-volume process, or isometric process. It is one of the processes in thermodynamics. Here are some questions that will be useful to test your knowledge of the isovolumetric process as well as practice. So, what are you waiting for? Let's go for these questions.

• 1.

### The isovolumetric process is a

• A.

Thermodynamic process taking place at changing volume

• B.

Thermodynamic process taking place at constant volume

• C.

Thermodynamic process taking place at no volume

• D.

None of these

B. Thermodynamic process taking place at constant volume
Explanation
The isovolumetric process is a thermodynamic process that takes place at constant volume. In this process, the volume of the system remains constant while other properties such as pressure, temperature, and internal energy may change. This means that no work is done by or on the system, as there is no change in volume. The isovolumetric process is also known as an isochoric process.

### Where has the term isochoric been derived from?

• A.

Japanese language

• B.

Medieval English

• C.

Roman language

• D.

Greek language

D. Greek language
Explanation
The term "isochoric" has been derived from the Greek language.

### What does "iso" mean in isochoric?

• A.

Constant

• B.

Changing

• C.

Volume

• D.

Weight

A. Constant
Explanation
In the term "isochoric," the prefix "iso" means constant. This can be inferred from the fact that "isochoric" is derived from the Greek words "iso" meaning equal and "choros" meaning space or volume. Therefore, "iso" in "isochoric" implies that the volume remains constant or unchanged.

### What does "choric" mean in isochoric?

• A.

Speed

• B.

Weight

• C.

Volume

• D.

Constant

C. Volume
Explanation
In the term "isochoric," the word "choric" refers to volume. Isochoric means a process or system that occurs at constant volume. Therefore, the correct answer is volume.

### In the isochoric process, the work done is

• A.

One

• B.

Always changing

• C.

Infinite

• D.

Zero

D. Zero
Explanation
In an isochoric process, also known as a constant volume process, the volume remains constant. This means that there is no expansion or compression of the system, and therefore no work is done. Work is defined as the force applied to an object multiplied by the distance over which the force is applied, but in an isochoric process, there is no change in volume, so no work is done. Therefore, the correct answer is zero.

### Which of these is not an example of an isovolumetric process?

• A.

A moving bus at the speed of 50Mph

• B.

The ideal otto cycle

• C.

The heating of the contents of a sealed inelastic container

• D.

The cooling of the contents of a sealed inelastic container

A. A moving bus at the speed of 50Mph
Explanation
The correct answer is "A moving bus at the speed of 50Mph". This is not an example of an isovolumetric process because isovolumetric processes occur at constant volume, meaning the volume of the system does not change. In the case of a moving bus, the volume of the system (the bus) is constantly changing as it moves through space, so it is not an isovolumetric process.

### Which of these is not an example of an isovolumetric process?

• A.

The freezing of water to turn into ice

• B.

The boiling of water to steam

• C.

Rapidly inflating a balloon with a helium tank.

• D.

None of these

C. Rapidly inflating a balloon with a helium tank.
Explanation
The isovolumetric process refers to a process in which the volume of a system remains constant. In the freezing of water to turn into ice and the boiling of water to steam, the volume of the water changes. However, when rapidly inflating a balloon with a helium tank, the volume of the balloon increases, indicating that it is not an isovolumetric process.

### Other than volume, what remains constant in the isochoric process?

• A.

Temperature

• B.

Entropy

• C.

Both A & B

• D.

None of these

D. None of these
Explanation
In an isochoric process, also known as a constant volume process, the volume remains constant. This means that the system does not experience any change in volume throughout the process. However, temperature and entropy are not constant in an isochoric process. Temperature can change due to the transfer of heat, and entropy can also change due to the irreversible nature of the process. Therefore, the correct answer is "None of these" as neither temperature nor entropy remains constant in an isochoric process.

### "n" is equal to what in an isovolumetric process?

• A.

Infinity

• B.

Ten

• C.

Hundred

• D.

One

A. Infinity
Explanation
In an isovolumetric process, the volume remains constant. Therefore, the value of "n" can be any number, including infinity. This means that "n" is not limited or restricted to a specific value and can be infinitely large.

• 10.

### In the isochoric process,

• A.

All parameters are constant.

• B.

Free expansion takes place.

• C.

Both A & B

• D.

None of these

D. None of these
Explanation
The given statement "In the isochoric process, all parameters are constant" is incorrect. In an isochoric process, also known as a constant volume process, the volume remains constant while other parameters such as pressure, temperature, and quantity of gas can change. Therefore, the correct answer is "None of these" as neither all parameters are constant nor does free expansion take place in an isochoric process.
