Water equivalent of a body is measured in

Options

A. kg
B. calorie
C. kelvin
D. `m^(3)`

Explanation

To solve the question regarding the water equivalent of a body, we can follow these steps:

### Step 1: Understand the Concept of Water Equivalent
The water equivalent of a body is defined as the mass of water that has the same heat capacity as the given body. This means that if we were to heat both the body and an equivalent mass of water, they would absorb the same amount of heat for the same temperature change.

**Hint:** Remember that water equivalent relates to mass and heat capacity.

### Step 2: Identify the Units of Measurement
Since the water equivalent is essentially a mass measurement, we need to identify the appropriate unit of measurement from the options provided:
- kg (kilograms)
- calorie
- kelvin
- meter cube

**Hint:** Focus on the physical quantity being measured (mass) to determine the correct unit.

### Step 3: Analyze the Options
- **kg (kilograms)**: This is a unit of mass.
- **calorie**: This is a unit of energy (heat).
- **kelvin**: This is a unit of temperature.
- **meter cube**: This is a unit of volume.

**Hint:** Eliminate options that do not relate to mass.

### Step 4: Conclusion
Since the water equivalent is defined in terms of mass, the correct unit of measurement for the water equivalent of a body is **kg** (kilograms).

### Final Answer
The water equivalent of a body is measured in **kg**.
