If radiation correction is not considered in specific heat measurement. The measured value of If radio specific heat will be

Options

A. more than its actual value.
B. less than its actual value.
C. remains same as actual value.
D. none of these.

Answer

To solve the question regarding the effect of neglecting radiation correction in specific heat measurement, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Formula for Specific Heat**:
The specific heat (c) is calculated using the formula:
\[ c = \frac{Q}{m \Delta T} \]
where \( Q \) is the heat added, \( m \) is the mass, and \( \Delta T \) is the change in temperature.

2. **Identify the Role of Radiation Correction**:
When measuring specific heat, radiation losses can affect the temperature change (\( \Delta T \)). If radiation correction is not considered, the measured temperature change may not reflect the true change in temperature due to heat loss.

3. **Effect of Neglecting Radiation Correction**:
If radiation correction is ignored, the temperature change (\( \Delta T \)) will be greater than the actual temperature change because some heat is lost to the surroundings. This leads to an overestimation of the specific heat.

4. **Conclusion on Measured Value**:
Since \( \Delta T \) is greater than its actual value when radiation correction is neglected, the calculated specific heat will also be greater than its actual value. Therefore, the measured specific heat will be more than its actual value.

5. **Choose the Correct Option**:
Based on the analysis, the correct answer is that the measured value of specific heat will be **more than its actual value**.

### Final Answer:
The measured value of specific heat, if radiation correction is not considered, will be **more than its actual value**.
