Which unit is used to express temperature in the material?

• A. Fahrenheit
• B. Kelvin
• C. Rankine
• D. Degrees Celsius

Answer: (D)

Temperature in material contexts is commonly expressed in degrees Celsius because it directly aligns with familiar phase-change references (0°C for freezing, 100°C for boiling) and fits the metric system used in labs and data sheets. This makes readings intuitive and easy to compare across experiments and material properties. Kelvin is the absolute scale and is essential for precise thermodynamic work or when dealing with extreme conditions, but for everyday material testing and standard charts, Celsius is more convenient and readable. Fahrenheit and Rankine are less common in technical material science contexts, so degrees Celsius is the typical choice.
