Thermometry & Thermal Expansion

Which of the following figure represents the relation between Celsius and Fahrenheit temperatures?

Show answer and solution

Answer: (d)

  1. C=59(F−32)=59F−1609C=\frac{5}{9}(F-32)=\frac{5}{9}F-\frac{160}{9}: a straight line with positive slope.
  2. At F=0F=0, C=−17.8C=-17.8 (negative intercept); C=0C=0 at F=32F=32 (positive F-intercept).
  3. Only graph (d) rises to the right and cuts the C-axis below the origin.
  4. So the answer is (d).
