At what temperature is water the most dense?

water is most dense at 3.98 C (or 39.16 F)

how does the length of the sun's path vary with the seasons?

AT +04C

Water is most dense at a temperature of approximately 4 degrees Celsius (39.2 degrees Fahrenheit). At this temperature, water molecules are packed closely together, resulting in a higher density compared to both colder and hotter temperatures.

To find this information, you can use reliable scientific sources such as textbooks, scientific journals, or reputable websites related to chemistry or physics. Alternatively, you can perform experiments to measure the density of water at various temperatures and observe the trend.
