Understanding Temperature Scales
Temperature is a measure of how hot or cold an object is relative to a standard. The three most common temperature scales are:
Celsius (°C)
- The Celsius scale is based on the freezing point of water at 0°C and the boiling point at 100°C.
- It is widely used around the world, especially in scientific contexts.
Fahrenheit (°F)
- The Fahrenheit scale sets the freezing point of water at 32°F and the boiling point at 212°F.
- Predominantly used in the United States and a few Caribbean nations.
Kelvin (K)
- The Kelvin scale is an absolute temperature scale starting at absolute zero (0 K), the point at which molecular motion stops.
- The freezing point of water is 273.15 K and the boiling point is 373.15 K.
Temperature Conversion Formulas
To effectively use a temperature conversion worksheet with answers, it is essential to understand the formulas used for converting between the different temperature scales. Here are the key conversion formulas:
Celsius to Fahrenheit
\[
°F = (°C \times \frac{9}{5}) + 32
\]
Fahrenheit to Celsius
\[
°C = (°F - 32) \times \frac{5}{9}
\]
Celsius to Kelvin
\[
K = °C + 273.15
\]
Kelvin to Celsius
\[
°C = K - 273.15
\]
Fahrenheit to Kelvin
\[
K = (°F - 32) \times \frac{5}{9} + 273.15
\]
Kelvin to Fahrenheit
\[
°F = (K - 273.15) \times \frac{9}{5} + 32
\]

Answers to the Temperature Conversion Worksheet
Now, let’s provide the answers to the worksheet with step-by-step solutions for clarity.
Solution to Each Problem
1. Convert 25°C to Fahrenheit.
- \( °F = (25°C \times \frac{9}{5}) + 32 \)
- \( °F = (25 \times 1.8) + 32 \)
- \( °F = 45 + 32 \)
- Answer: 77°F
2. Convert 68°F to Celsius.
- \( °C = (68°F - 32) \times \frac{5}{9} \)
- \( °C = (36) \times \frac{5}{9} \)
- \( °C = 20 \)
- Answer: 20°C
3. Convert 100°C to Kelvin.
- \( K = 100°C + 273.15 \)
- \( K = 373.15 \)
- Answer: 373.15 K
4. Convert 32°F to Kelvin.
- \( K = (32°F - 32) \times \frac{5}{9} + 273.15 \)
- \( K = (0) \times \frac{5}{9} + 273.15 \)
- \( K = 273.15 \)
- Answer: 273.15 K
5. Convert 300 K to Celsius.
- \( °C = 300 K - 273.15 \)
- \( °C = 26.85 \)
- Answer: 26.85°C
6. Convert 212°F to Celsius.
- \( °C = (212°F - 32) \times \frac{5}{9} \)
- \( °C = (180) \times \frac{5}{9} \)
- \( °C = 100 \)
- Answer: 100°C
7. Convert 0°C to Fahrenheit.
- \( °F = (0°C \times \frac{9}{5}) + 32 \)
- \( °F = (0) + 32 \)
- Answer: 32°F
8. Convert 400 K to Fahrenheit.
- \( °F = (400 K - 273.15) \times \frac{9}{5} + 32 \)
- \( °F = (126.85) \times 1.8 + 32 \)
- \( °F = 228.33 + 32 \)
- Answer: 260.33°F
9. Convert 50°F to Kelvin.
- \( K = (50°F - 32) \times \frac{5}{9} + 273.15 \)
- \( K = (18) \times \frac{5}{9} + 273.15 \)
- \( K = 10 + 273.15 \)
- Answer: 283.15 K
10. Convert -40°C to Fahrenheit.
- \( °F = (-40°C \times \frac{9}{5}) + 32 \)
- \( °F = (-72) + 32 \)
- Answer: -40°F
