According to Laplace correction, the propagation of sound in gas takes place under

Options

A. isothermal condition
B. isobaric condition
C. isochoric condition
D. adiabatic condition

Answer

To solve the question regarding the propagation of sound in gas according to Laplace correction, we can follow these steps:

### Step 1: Understand the Context
The question asks about the conditions under which sound propagates in a gas according to Laplace's correction. It is important to know what Laplace's correction refers to in the context of sound propagation.

### Step 2: Identify the Conditions
The options provided are:
- Isothermal condition
- Isobaric condition
- Isochoric condition
- Adiabatic condition

### Step 3: Define Each Condition
- **Isothermal Condition**: Temperature remains constant during the process.
- **Isobaric Condition**: Pressure remains constant during the process.
- **Isochoric Condition**: Volume remains constant during the process.
- **Adiabatic Condition**: No heat exchange occurs with the surroundings; the process is characterized by changes in pressure and volume without heat transfer.

### Step 4: Apply Laplace's Correction
According to Laplace's correction, the propagation of sound in a gas occurs under adiabatic conditions. This means that when sound waves travel through a gas, the process involves rapid compressions and rarefactions, which do not allow heat exchange with the environment.

### Step 5: Conclusion
Based on the understanding of the conditions and Laplace's correction, the correct answer is:
**Adiabatic condition.**

### Final Answer:
The propagation of sound in gas takes place under **Adiabatic condition**.
