There is always some loss of energy in conversion from one form of energy to another form, so the total energy is not conserved. True/False.

Answer

To determine whether the statement "There is always some loss of energy in conversion from one form of energy to another form, so the total energy is not conserved" is true or false, we can analyze the concepts of energy conversion and conservation.

### Step-by-Step Solution:

1. **Understanding Energy Conversion**:
- Energy can be converted from one form to another, such as mechanical energy to kinetic energy, electrical energy to light energy, etc.

2. **Identifying Energy Loss**:
- During these conversions, there are often resistive forces or inefficiencies that cause some energy to be lost. For instance, when an engine converts fuel into mechanical energy, some energy is lost as heat due to friction.

3. **Examples of Energy Loss**:
- A common example is a light bulb. When it converts electrical energy into light energy, not all the electrical energy is converted into light; some is lost as heat. This heat is considered wasted energy in the context of the desired output.

4. **Total Energy Conservation**:
- The principle of conservation of energy states that energy cannot be created or destroyed; it can only change forms. However, in practical scenarios, while energy is conserved in total, some of it is transformed into less useful forms (like heat), which may not contribute to the intended work.

5. **Conclusion**:
- Therefore, while the total amount of energy remains constant, the useful energy decreases due to losses in conversion processes. Thus, the statement is **True** in practical terms, as energy is not fully conserved in useful forms during conversions.

### Final Answer:
**True** - There is always some loss of energy in conversion from one form of energy to another form, so the total energy is not conserved.
