To analyze the statements regarding the energy transformation of light bulbs with a 120 V source, we need to consider the power ratings of the bulbs and how they relate to energy consumption over a given duration.
1. **The 60 W bulb transforms an equivalent quantity of electrical energy into both heat and light compared to a 100 W bulb.**
- **False:** The 60 W bulb transforms less electrical energy compared to a 100 W bulb because it draws less power (60 watts vs. 100 watts) over the same duration.
2. **The 60 W bulb transforms a smaller amount of electrical energy into both heat and light compared to a 100 W bulb.**
- **True:** The 60 W bulb consumes less energy than a 100 W bulb when both are connected to a 120 V source for the same duration, hence it transforms a smaller amount of electrical energy.
3. **The 60 W bulb transforms an equal quantity of electrical energy into both heat and light when compared to a 40 W bulb.**
- **False:** The 60 W bulb consumes more energy than a 40 W bulb when both are used for the same duration. Therefore, it does not transform an equal quantity of energy.
4. **The 60 W bulb converts a smaller amount of electrical energy into both heat and light compared to a 40 W bulb.**
- **False:** The 60 W bulb consumes more energy than a 40 W bulb. Therefore, it does not convert a smaller amount of electrical energy; it converts a greater amount.
In summary, only the second statement is true.
