8. A scoop of ammonium nitrate is added to a beaker of water. Which is a quantitative observation of the experiment? A. The ammonium nitrate dissolved in the water.
B. The temperature of the water decreased by 5°C.
C. A chemical reaction occurred.
D. The solution did not change color.

The correct answer is B. The temperature of the water decreased by 5°C

Explanation:

Temperature and the changes in it are part of quantitative observations because these can only be measured and understood through numbers. Indeed, the temperature is globally measured through different numerical scales such as the Celsius or the Kelvin scale. This does not occur in other qualities such as color because this is considered and analyzing using qualities or traits rather than values. According to this, the correct answer is "The temperature of the water decreased by 5°C."
