Quizplus · Accepted Answer

To convert from Celsius to Fahrenheit, we use the formula F = (9/5)C + 32. Therefore, we can find the Fahrenheit temperature change by plugging in 20 for C and solving for F:
F = (9/5)(20) + 32
F = 36 + 32
F = 68
Therefore, the Fahrenheit temperature change is 68°F. The closest answer choice to this is C, which is 36°F. However, 36 is not the correct answer, as it would correspond to a Celsius temperature change of 20/1.8 = 11.11°C.
