A steam engine converts the heat energy of steam into

Options

A. electrical energy
B. nuclear energy
C. mechanical energy
D. none of these

Answer

To solve the question "A steam engine converts the heat energy of steam into", we will analyze the options provided and understand the working principle of a steam engine.

### Step-by-Step Solution:

1. **Understanding the Function of a Steam Engine**:
- A steam engine operates by converting heat energy from steam into another form of energy.

2. **Identifying the Type of Energy Produced**:
- The primary function of a steam engine is to perform work. In this case, the work done is mechanical work.

3. **Analyzing the Options**:
- **Option 1: Electrical Energy** - This is not correct as a steam engine does not primarily convert heat energy into electrical energy.
- **Option 2: Nuclear Energy** - This is also incorrect as nuclear energy is derived from nuclear reactions, not from steam.
- **Option 3: Mechanical Energy** - This is correct. A steam engine converts heat energy into mechanical energy to perform work.
- **Option 4: None of These** - This option is incorrect since we have identified that mechanical energy is produced.

4. **Conclusion**:
- Based on the analysis, the correct answer is **Option 3: Mechanical Energy**.

### Final Answer:
A steam engine converts the heat energy of steam into **mechanical energy**.
