Statement 1: A gas has a unique value of specific heat.
Statement 2: Specific heat is defined as the amount of heat required to raise the temperature of unit mass of the substance through unit degree.

Explanation

To analyze the statements provided in the question, we will break down each statement and evaluate its correctness step by step.

### Step 1: Evaluate Statement 1
**Statement 1:** A gas has a unique value of specific heat.

- **Analysis:**
- Specific heat is defined as the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius (or one Kelvin).
- For gases, the specific heat can vary depending on the conditions under which the gas is measured. Specifically, there are two common conditions: constant volume (Cv) and constant pressure (Cp).
- Thus, a gas does not have a unique value of specific heat; it can have different values based on the conditions (Cv and Cp) and can also change with temperature.

**Conclusion for Statement 1:** This statement is **false**.

### Step 2: Evaluate Statement 2
**Statement 2:** Specific heat is defined as the amount of heat required to raise the temperature of unit mass of the substance through unit degree.

- **Analysis:**
- The definition provided in Statement 2 is generally correct; specific heat is indeed defined as the amount of heat required to raise the temperature of a unit mass of a substance by one degree.
- However, the specific heat can vary depending on the conditions (e.g., whether the process occurs at constant volume or constant pressure) and can also depend on the temperature of the substance.
- Therefore, while the definition is accurate, it does not account for the fact that specific heat can change under different conditions.

**Conclusion for Statement 2:** This statement is **partially true** but misleading as it does not emphasize the variability of specific heat under different conditions.

### Final Conclusion
- **Statement 1:** False
- **Statement 2:** Partially true but misleading

### Summary
Both statements have inaccuracies regarding the concept of specific heat. Statement 1 is clearly false, while Statement 2 lacks the necessary context about the variability of specific heat.
