Question

The density of water is maximum at _______ equal to 1000 kg m⁻³. *​

Answer 1

It means that under standard of pressure, and temperature, a cubic metre volume (truly a LARGE volume) of water has a mass of  1000∙kg ….

And we know that  1∙m3≡1000∙L , and  11000×11000∙m3≡1∙mL≡1∙cm3≡10−6∙m3 , the which has a mass of  1∙g .

That is  ρthe density of water≡1∙g∙mL−1≡1∙g∙cm−3≡103∙kg∙m−3 ….

Answer 2

Answer:

Density of water is the highest at 40C. Above 40C, the water molecules can not come closer due to thermal motion.
