A Correct answer
Explanation

Cold water is denser than hot water. When water is heated, the molecules gain kinetic energy and move further apart, increasing volume while mass stays constant. This means a given volume of cold water contains more mass (weighs more) than the same volume of hot water. The density difference is most pronounced near 4°C.
