oil has a low boiling point than water. Therefore we use oil to make the cooking process faster and easier

Ans 2:

Class : Class 9
We fry stuff in oil because oil has much higher boiling point in comparison to water. So after heating when oil reaches temperatures greater than the boiling point of water (100 C) it instantly vaporize the water present in food into steam. ... Oil fries it and gives a crispy texture.
