Like air, water expands as it gets warmer and as a result becomes less dense. Water is most dense at temperatures near freezing. When water freezes, however, it expands, becoming less dense. If equal volumes of cold water (down to 4deg.C, 39.2deg.F) and hot water are compared, cold water weighs more than hot water.
