Class 8 Science Curiosity Textbook Chapter 1 Exploring the Investigative World of Science question answer
When a puri or batura is placed in hot oil, the heat causes moisture in the dough to turn into steam. This steam gets trapped inside, creating pressure that inflates the dough, forming a puff. The outer layer cooks quickly, holding the shape. This process shows how heat, moisture and material structure interact. It’s a perfect everyday example of scientific principles like pressure, heat transfer and changes in states of matter.
