Question

10. The boiling of rice is a physical change.

• A. True
• B. False

Answer 1

The correct option is B False

• A change during which only the physical properties of a substance change, is called a physical change.
• The boiling of rice is a chemical change as the starch granules absorb water and expand as they are heated.
• The cell wall of the rice granule breaks when the gelatinization temperature is reached.
• The starch granules become viscous or transform into amylase and amylopectin.
• Therefore, the given statement is false.
