CBSE · Class 11 · Physics · Thermal Properties of MatterAt what temperature does water reach its maximum density?
Step-by-Step Solution
Water exhibits anomalous expansion between $0^\circ\text{C}$ and $4^\circ\text{C}$. As water is heated from $0^\circ\text{C}$ to $4^\circ\text{C}$, its volume decreases and density increases, reaching a maximum at $4^\circ\text{C}$. Hence, option A is correct.
