Question 8. Why is one side of a puri thinner than the other? (Page 6)

Answer: When a puri is fried, steam forms inside it and causes the puri to puff up. Sometimes, one side stretches more than the other and becomes thinner. This may depend on the thickness of the dough, the temperature of the oil, and the way the puri is placed in the oil.

Question 9. Do puris puff better when made fresh or from stored dough? (Page 7)

Answer: Puris usually puff better when they are made from fresh dough. Fresh dough has the right amount of moisture and softness, which helps the puri puff properly during frying. Stored dough may become dry or hard, so the puri may not puff well.

Question 10. What is a systematic investigation? (Page 7)

Answer: A systematic investigation is a planned method of finding answers to a question. In this method, only one factor is changed at a time, while all other factors are kept the same. Careful observations are made, measurements are taken, and results are recorded accurately.
