\nThe statement “As ice melts, it expands uniformly up to 4\u00b0C” is not correct.
\n<\/section>\n
\nMost substances expand when heated, but water exhibits anomalous expansion between 0\u00b0C and 4\u00b0C. When ice melts at 0\u00b0C, it forms liquid water which is denser than ice. As liquid water is heated from 0\u00b0C to 4\u00b0C, it *contracts* and its density increases, reaching maximum density at 4\u00b0C. Only above 4\u00b0C does water expand like most other substances when heated. Therefore, the statement that water expands uniformly up to 4\u00b0C after melting is incorrect; it contracts from 0\u00b0C to 4\u00b0C.
\n<\/section>\n
\nStatements B, C, and D are correct applications or observations of thermal expansion. Mercury thermometers work because mercury expands linearly with temperature. Gaps in railway tracks prevent buckling caused by the linear expansion of the rails on hot days. Metallic wires also undergo linear expansion when heated, increasing their length. The anomalous expansion of water is crucial for aquatic life in cold climates, as the densest water (at 4\u00b0C) sinks to the bottom, preventing lakes from freezing solid from top to bottom.
