Earth
Class MThe blue marble. Sustains water in all three phases with a stable nitrogen-oxygen atmosphere.
Understanding Temperature Scales
Temperature measures average molecular kinetic energy. We quantify this using three scales: relative Celsius (°C) and Fahrenheit (°F), and absolute thermodynamic Kelvin (K).
Standard Conversion Equations
A 1°C shift equals 1 K, or 1.8°F. The 32 offset aligns their zero points.
Comparison of Fixed References
Absolute Zero: -273.15°C | -459.67°F | 0 K
Intersect Temp: -40°C | -40°F | 233.15 K
Water Freezes: 0°C | 32°F | 273.15 K
Water Boils: 100°C | 212°F | 373.15 K
Physical Meaning of Kelvin
Kelvin is anchored to absolute zero (0 K), the state of minimal energy. Physics equations (like the Ideal Gas Law) require absolute thermodynamic temperature in Kelvins.
Solved Examples
Convert Mars night temperature (-143°C) to Fahrenheit and Kelvin.
- T(°F) = -143 × 1.8 + 32 = -225.4°F
- T(K) = -143 + 273.15 = 130.15 K
-143°C = -225.4°F = 130.15 K
Convert Venus surface temperature (864°F) to Celsius and Kelvin.
- T(°C) = (864 - 32) / 1.8 = 462.22°C
- T(K) = 462.22 + 273.15 = 735.37 K
864°F ≈ 462.22°C ≈ 735.37 K
Common Algebra Pitfalls
- Order: Multiply Fahrenheit by 1.8 before subtracting 32 (subtract first).
- Signs: Adding 32 instead of subtracting when converting Fahrenheit to Celsius.
- Kelvin: Writing °K instead of K. Kelvin uses no degree symbol.
Scale Interval Ratios
- 1°C change = 1 K change.
- 1°C change = 1.8°F change.
- 10°C change = 18°F change = 10 K change.
Practice Questions
