Options

A. water equivalent
B. thermal capacity
C. specific heat
D. temperature gradient

Explanation

To solve the question regarding the heat given to a body that raises its temperature by \(1^\circ C\), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Specific Heat**:
- The specific heat of a substance is defined as the amount of heat required to raise the temperature of one unit mass of the substance by \(1^\circ C\) (or \(1 \text{ K}\)).
- Mathematically, it is expressed as:
\[ c = \frac{Q}{m \Delta T} \]
where:
- \(c\) = specific heat,
- \(Q\) = heat added,
- \(m\) = mass of the substance,
- \(\Delta T\) = change in temperature.

2. **Identifying the Heat for \(1^\circ C\)**:
- If we want to find the heat \(Q\) that raises the temperature of a body by \(1^\circ C\), we can rearrange the formula:
\[ Q = m \cdot c \cdot \Delta T \]
- For our case, since \(\Delta T = 1^\circ C\), we have:
\[ Q = m \cdot c \cdot 1 \]
- Therefore, the heat given to the body which raises its temperature by \(1^\circ C\) is simply:
\[ Q = m \cdot c \]

3. **Conclusion**:
- The heat given to a body which raises its temperature by \(1^\circ C\) is equal to the specific heat of the body multiplied by its mass.
- If we consider the specific heat alone (without mass), the heat given to raise the temperature by \(1^\circ C\) can be referred to as the specific heat \(c\).

### Final Answer:
The heat given to a body which raises its temperature by \(1^\circ C\) is the specific heat of the body.
