The amount of heat required to raise the temperature of a substance through `1^(@)C` is called

Options

A. thermal energy
B. Calorie
C. heat capacity
D. specific heat capacity

Explanation

To solve the question, "The amount of heat required to raise the temperature of a substance through 1°C is called," we need to identify the correct term that describes this concept in physics.

### Step-by-Step Solution:

1. **Understanding the Concept**:
- When we want to raise the temperature of a substance by a certain amount, we need to supply heat. The amount of heat required to raise the temperature of a substance by 1 degree Celsius is a specific measurement.

2. **Identifying the Terms**:
- The question provides several options that might relate to the amount of heat required:
- Thermal Energy
- Calorie
- Heat Capacity
- Specific Heat Capacity

3. **Evaluating Each Option**:
- **Thermal Energy**: This term refers to the total energy of the particles in a substance due to their motion. It is not specific to raising the temperature by 1°C.
- **Calorie**: This is a unit of measurement for heat, not a specific term for the heat required to raise the temperature by 1°C.
- **Heat Capacity**: This term refers to the amount of heat required to raise the temperature of a substance by 1°C, but it does not specify the mass of the substance.
- **Specific Heat Capacity**: This term refers to the amount of heat required to raise the temperature of 1 kg of a substance by 1°C. It is a more specific measurement that takes into account the mass of the substance.

4. **Conclusion**:
- The correct answer to the question is **Heat Capacity**. It describes the amount of heat required to raise the temperature of a substance by 1°C without specifying the mass.

### Final Answer:
The amount of heat required to raise the temperature of a substance through 1°C is called **Heat Capacity**.
