`Delta"Q"=nCdT` represents

Options

A. Change in amount of heat contained in a body as a result of temperature change
B. Amount of heat energy which transists from one body to other due to temperature difference
C. Both (Change in amount of heat contained in a body as a result of temperature change) and (Amount of heat energy which transits from one dody to other due to temperature difference) are correct
D. None of these

Answer

To solve the question regarding the equation ΔQ = nCΔT, we will break it down step by step.

### Step-by-Step Solution:

1. **Understanding the Variables**:
- ΔQ: Represents the change in heat energy.
- n: Represents the number of moles of the substance.
- C: Represents the specific heat capacity of the substance.
- ΔT: Represents the change in temperature.

2. **Interpreting the Equation**:
- The equation ΔQ = nCΔT indicates that the change in heat energy (ΔQ) is directly proportional to the number of moles (n), the specific heat capacity (C), and the change in temperature (ΔT).

3. **Physical Meaning**:
- This equation is used to calculate the amount of heat absorbed or released by a substance when its temperature changes. It shows that if you know the number of moles of a substance, its specific heat, and the temperature change, you can calculate the change in heat energy.

4. **Analyzing the Options**:
- Option A: "The change in amount of heat contained in a body as the result of temperature change." This is correct as ΔQ represents the change in heat due to a temperature change.
- Option B: "Amount of heat which transits from one body to another due to temperature difference." This is also correct because ΔQ can represent heat transfer due to temperature differences.
- Option C: "Both A and B." Since both A and B are correct, this option is also correct.

5. **Conclusion**:
- The correct answer is option C: "Both A and B."
