Question

at what temperature is water most dense? 20 degrees celsius 50 degrees celsius 95 degrees celsius 4 degrees celsius

Explanation:

Water's density changes with temperature. Due to hydrogen bonding and molecular arrangement, water reaches its maximum density at 4 degrees Celsius. As temperature increases above or decreases below this point, density decreases (e.g., water expands when freezing below 0°C).

Answer:

4 degrees Celsius
