The size of one degree of Celsius is equal to_________________?
Correct answer: B. 1.8 degrees of Fahrenheit scale
- A. One degree of Fahrenheit scale
- B. 1.8 degrees of Fahrenheit scale
- C. 3.2 degrees of Fahrenheit scale
- D. 2.12 degrees of Fahrenheit scale
Explanation
The interval conversion is ΔF = (9/5)ΔC. Hence, a change of 1°C corresponds to (9/5) × 1 = 1.8°F, so it is 1.8 degrees on the Fahrenheit scale. The likely mistake is choosing 1°F by treating the degree sizes as identical rather than using the scale 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.
