Important exam questions with answers
Why does one side of a puri become thinner than the other when it puffs up during frying?
One side of the puri becomes thinner because the dough's thickness is not uniform, and steam inside pushes the dough unevenly. This causes one side to puff more and become thinner. (2 points: explanation of steam causing puffing and uneven dough thickness)
Explain how curiosity can lead to scientific investigation with an example from daily life.
Curiosity leads to asking questions like why dough rises when making bread. Investigating this involves observing yeast producing carbon dioxide, which causes dough to rise. (2 points: mention of curiosity and example of yeast fermentation)
How does scientific knowledge change over time? Give an example mentioned in the chapter.
Scientific knowledge changes as new evidence emerges; for example, the old belief that Earth was the universe's center was replaced by the understanding that Earth revolves around the Sun. (2 points: mention of evolving science and example of heliocentric model)
