At what temperature is the Fahrenheit scale reading equal to twice that of the Celsius scale?
Correct answer: D. 160°C
- A. 460°C
- B. 280°C
- C. 360°C
- D. 160°C
Explanation
Use F = (9/5)C + 32 and set the Fahrenheit reading equal to twice the Celsius reading: 2C = (9/5)C + 32, so (1/5)C = 32 and C = 160°C. Therefore, the temperature is 160°C. The common trap is 360°C, which results from mishandling the 9/5 conversion factor.

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
