Answer 2

Answer:  

When milk is kept in the refrigerator, the change that we get to observe is that its shelf life extends and it stays fresh for a long time period.  

Explanation:  

Boiled milk or otherwise, must be stored in a temperature less than 40 degrees F to keep it safe for a longer time period. If milk is not stored in the fridge, it gets spoiled, curdled and bacteria develop in it making it unfit for human consumption. In the fridge, milk stays in its cold form, and for a longer time remains fresh.
