Question

Sheela cooked rice in a rice cooker. What kind of change took place?
(i) Irreversible change
(ii) Endothermic change
(iii) Natural change

• A. Only (i) and (ii)
• B. Only (ii) and (iii)
• C. Only (i) and (iii)
• D. (i), (ii) and (iii)

Answer 1

The correct option is A

Only (i) and (ii)

The cooking of rice is a man-made process where heat is applied. Thus, this is an endothermic process. Once the rice is cooked, there is no mechanism to get back the original raw rice. Hence, the entire change is an irreversible endothermic man-made change.
