The correct Answer is:
To find out what 1 Joule equals to in terms of calories, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Definition of a Joule**: - A Joule (J) is a unit of energy in the International System of Units (SI). It is defined as the amount of energy transferred when a force of one newton is applied over a distance of one meter. 2. **Conversion Factor**: - We know from physics that 1 Joule is approximately equal to 0.239 calories. This conversion factor is essential for converting between these two units of energy. 3. **Rounding the Value**: - The value of 0.23905057361 can be rounded to a more manageable number for practical purposes. We can round it to 0.24 calories for simplicity. 4. **Final Conclusion**: - Therefore, we conclude that 1 Joule is approximately equal to 0.24 calories. ### Answer: 1 Joule = 0.24 calories. ---
