Volume and Density versus Water Temperature

Temperature (Celsius) Volume of 1.000 gram of water (cc or mL) Density ( g/cc or g/mL)
0 (ice) 1.0928 0.9150
4 1.0000 1.000
20 1.0018 0.9982
40 1.0079 0.9922
60 1.0171 0.9832
80 1.0290 0.9718

Water changes density with changing temperature. At what temperature in Celsius does water have its smallest density value?
