During the interconversion of states, which property remains constant? MCQ with Answer and Explanation

During the interconversion of states, which property remains constant?
A. Shape
B. Density
C. Volume
D. Mass
Answer: Option D
Solution (By JKExamLibrary)
According to the law of conservation of mass, the mass of a substance remains constant during any physical change, including the interconversion of states. Density, volume, and shape change as the intermolecular spaces and arrangement alter during phase transitions, but the total number of atoms and mass is conserved.

Baking soda on heating produces:
A. Na₂CO₃, CO₂, and H₂O
B. Na and CO₂
C. NaHCO₃ only
D. Na₂O and CO₂

Correct Answer: Option A


Explanation:
2NaHCO₃ (heat) → Na₂CO₃ + CO₂ + H₂O. This is used in baking as CO₂ causes dough to rise. The sodium carbonate formed gives a bitter taste if excess soda is used, hence baking powder (with acid) is preferred.
