Why is the base of a cooking pan generally made thick?
Why is the base of a cooking pan made thick and heavy?
उत्तर
By making the base of a cooking pan thick, its thermal capacity becomes large and it imparts sufficient heat energy at a low temperature to the food for proper cooking. Further, it keeps the food warm for a long time after cooking.
