• # question_answer When water is heated from ${{0}^{o}}C$to${{10}^{o}}C$. Its volume: A)  increases B)  decreases C)  does not change D)  first decreases and then increases

Initially at start of heating from ${{0}^{o}}C$ to ${{4}^{o}}C$ there will be a contraction as a result of which volume decreases. On further heating beyond ${{4}^{o}}C$ to ${{10}^{o}}C$ the molecules gain kinetic energy and start moving more randomly. Thus, intermolecular distance increases as a result of which its volume increases.
