Physical changes are usually _______ in nature.
Physical changes are usually _______ in nature.
The correct option is A temporary
Explanation for correct option:
A: Physical change refers to a change in the physical properties of a substance like its shape, size, and color. It simply affects a substance's appearance and not its chemical composition.
Physical change is generally reversible or temporary in nature.
For examples: Melting of ice, freezing, cutting, and bending.
Explanation for incorrect options:
B: Physical change is not permanent. It is temporary.
C: Physical change can be reversed. Hence, it is not irreversible.
D: The chemical reactions in which heat is absorbed are known as endothermic. Therefore, endothermic reactions are not associated with a physical change.
Final answer:
Hence, option (A) is correct. Physical changes are usually temporary in nature.
