Water is Densest At

Question

Water is densest at
A)⁻4°C.
B)0°C.
C)2°C.
D)4°C.
E)8°C.

Accepted Answer

Water reaches its maximum density at 4°C. At this temperature, the water molecules are closest together, resulting in the highest density. As the temperature continues to decrease or increase, the water molecules move farther apart, resulting in a decrease in density. Therefore, water is less dense at both 0°C and ⁻4°C compared to 4°C.
