Question

Why pressure of water is highest at 4 celcius

Answer 1

When the ice melts to liquid water, the structure collapses and the density of the liquid increases. At temperatures well above freezing, the molecules move faster and get further apart. The density decreases as temperature increases. ... Thus, the density of water is a maximum at 4 °C.

Answer 2

hey here is ur ans ..

4 degrees C turns out to be the temperature at which liquid water has the highest density. If you heat it or cool it, it will expand. The expansion of water when you cool it to lower temperatures is unusual, since most liquids contract when they're cooled...
