The density of water is the greatest at a temperature of

a. 0 K.

b. 273 K.

c. 4 K.

d. 277 K.

d. 277 K.

actually the answer is D,

Water has the highest density at 4 degrees celsius because of which warm water forms a layer beneath ice in the North allowing marine species to survive. 227K equates to 3.85 Celsius the closest temperature to 4 degrees celsius.

A. 0

Water’s solid form is less dense than its liquid form, while the opposite is true of most other substances.

For example, the Ice.

Notice that the ice is a solid form of the water but when you put the ice in the water, it floats. That makes it denser than the water itself. This happens because the hydrogen bonds cause the molecules to push farther apart with each other which result to lower density of the solid form of water.
