280 degrees Celsius is equal to degrees Fahrenheit. A. 140 B. 500 C. 536 D. 518
The correct answer and explanation is:
To convert 280 degrees Celsius to Fahrenheit, use the following formula: °F=(°C×95)+32°F = (°C \times \frac{9}{5}) + 32
Step-by-step calculation:
°F=(280×95)+32°F = (280 \times \frac{9}{5}) + 32 °F=(280×1.8)+32°F = (280 \times 1.8) + 32 °F=504+32=536°F°F = 504 + 32 = 536°F
✅ Correct answer: C. 536
🔍 Explanation (300 words):
Temperature can be measured in several units, with Celsius (°C) and Fahrenheit (°F) being the most commonly used. Celsius is widely used in most parts of the world, while Fahrenheit is mainly used in the United States.
The Celsius to Fahrenheit conversion formula is: °F=(°C×95)+32°F = (°C \times \frac{9}{5}) + 32
This formula reflects the relationship between the two temperature scales:
- The freezing point of water is 0°C or 32°F.
- The boiling point of water is 100°C or 212°F.
The multiplication by 9/5 (or 1.8) accounts for the difference in scale size (Fahrenheit degrees are smaller), and the addition of 32 shifts the scale to align freezing points.
In the case of 280°C, this is a very high temperature, well beyond boiling water. It’s often found in industrial ovens or furnaces. When converting it:
- Multiply 280 by 1.8 to scale it up to the Fahrenheit system → 504
- Then add 32 to shift the scale → 536°F
Understanding this conversion is important in fields like science, engineering, cooking, and manufacturing, where precise temperature control is critical. A mistake in conversion could lead to incorrect settings and potentially harmful outcomes.
So, using the formula correctly, 280°C = 536°F, and the correct answer is C. 536.
