Question

why do we keep a fridge in our home for class 8​

Answer 1

Answer:

The fundamental reason for having a refrigerator is to keep food cold. Cold temperatures help food stay fresh longer. The basic idea behind refrigeration is to slow down the activity of bacteria (which all food contains) so that it takes longer for the bacteria to spoil the food.

Answer 2

Answer:

Refrigerators maintain low temperature. At low temperature microorganisms become inactive which prevents the food decay. Hence, we are advised to keep the food in refrigerators.
