When temperature changes during the day, which scale, Celsius or Fahrenheit, will read a smaller change? and why?
Celsius, since its degrees are more widely separated.
1°C = 9/5°F, so a change of 9°F will only be a 5°C change.

To determine which scale, Celsius or Fahrenheit, will read a smaller change in temperature during the day, we need to understand the differences between the two scales.
Celsius (°C) and Fahrenheit (°F) are both commonly used temperature scales, but they have different reference points and unit sizes.
In the Celsius scale, the freezing point of water is defined as 0°C, and the boiling point of water is defined as 100°C. On the other hand, in the Fahrenheit scale, the freezing point of water is defined as 32°F, and the boiling point of water is defined as 212°F.
Now, let's consider a scenario where the temperature changes from 20°C to 25°C and from 68°F to 77°F.
To find the temperature change in Celsius, we subtract the starting temperature from the ending temperature: 25°C - 20°C = 5°C.
To find the temperature change in Fahrenheit, we subtract the starting temperature from the ending temperature: 77°F - 68°F = 9°F.
From this example, we can see that the change in Celsius (5°C) is smaller than the change in Fahrenheit (9°F).
The reason for this is that the Celsius scale has a smaller unit size compared to the Fahrenheit scale. In Celsius, the difference from freezing to boiling point (100 units) is divided into 100 increments, while in Fahrenheit, the difference (180 units) is divided into 180 increments.
So, to answer your question, when the temperature changes during the day, Celsius will usually read a smaller change compared to Fahrenheit because the Celsius scale has smaller unit sizes.
