Quantitative data is a type of data that can be measured using numbers or is dealt with objectively. These include various types of data like temperature, weight, length, prices, area, volume, etc. now these data can be measured quantitatively.

Apples turn brown when exposed to air because it undergoes aerial oxidation. Due to this, when the inside of the apple is exposed to the air containing oxygen and water, it turns brown. When apple is uncut, skin of the apple protects it from this process.
If the peeled apple in kept in the refrigerator, the oxidation reaction is greatly slowed down. This is because, rate of chemical reaction decreases with temperature. Hence, in refrigerator it would take several days for it to turn brown.
