उत्तर
A refrigerator is used in almost every home because it prevents the spoilage of food. Refrigerator provides an optimum environment for storage of vegetables, fruits, and cooked and uncooked food. If an optimum temperature is not provided, it can lead to the growth of bacteria and fungi, thus leading to spoilage of food.
