Convert the temperature of scalding water, 54 °C, into degrees Fahrenheit and kelvin.
The correct answer and explanation is:
To convert the temperature of scalding water (54 °C) into degrees Fahrenheit (°F) and Kelvin (K):
✅ Correct Answers:
- Fahrenheit (°F):
°F=(54×95)+32=129.2 °F°F = (54 × \frac{9}{5}) + 32 = 129.2 °F - Kelvin (K):
K=54+273.15=327.15 KK = 54 + 273.15 = 327.15 K
🔍 Detailed Explanation (Approx. 300 words):
Temperature is a measure of the average kinetic energy of particles in a substance. Different temperature scales are used around the world: Celsius (°C), Fahrenheit (°F), and Kelvin (K) are the most common. When measuring physical phenomena like the scalding point of water, accurate conversions are essential in science, nursing, and cooking.
1. Celsius to Fahrenheit:
To convert from Celsius to Fahrenheit, the formula is: °F=(°C×95)+32°F = (°C × \frac{9}{5}) + 32
Let’s apply it to 54 °C: °F=(54×95)+32=(54×1.8)+32=97.2+32=129.2 °F°F = (54 × \frac{9}{5}) + 32 = (54 × 1.8) + 32 = 97.2 + 32 = 129.2 °F
This temperature is considered scalding, meaning it’s hot enough to cause burns in seconds — particularly important in healthcare and food safety.
2. Celsius to Kelvin:
Kelvin is the SI (International System) unit for temperature, used especially in scientific calculations. The formula is: K=°C+273.15K = °C + 273.15
Applying it to 54 °C: K=54+273.15=327.15 KK = 54 + 273.15 = 327.15 K
The Kelvin scale starts at absolute zero, the point where particles have minimal thermal motion. It’s commonly used in physics and chemistry.
3. Real-World Relevance:
Understanding temperature conversions is crucial in healthcare, especially in wound care, sterilization, or safety assessments. Scalding injuries often occur at temperatures just over 120 °F. Knowing that 54 °C equals 129.2 °F emphasizes how quickly such temperatures can damage skin tissue.
In summary, 54 °C = 129.2 °F = 327.15 K, and these conversions are not only mathematical but also vital for real-world safety and scientific accuracy.
