Question

Why is this statement false?

As the temperature of water is decreased from 4C to 0C contraction occurs.

Answer 1

There is not contraction, Instead expansion occurs .

We know density of water is temperature dependant .

at 4°C water has max density so least volume as density is indirectly proportional to volume.

at 0°C density decreases so volume increases

Answer 2

The statement is false because as the temperature of water is decreased from 4C to 0C, expansion occurs.

You should understand that this is very weird behavior for any compound ... within a small temperature range, the stuff actually gets bigger as it gets colder. That's why cubes float in your sody, and bergs float in the ocean.

Water is one of only two known substances that do this. And if water didn't do it, then life on Earth would not be possible.

Hmmm....
