Question

Select the correct answer. Density is mass divided by volume (d = m ÷ v). Based on the graph, what happens to a fixed mass of water when it is cooled from 4°C to 0°C? A. volume increases and density decreases B. volume decreases and density increases C. volume increases and density increases D. volume decreases and density decreases

Answer 1

C.

Volume increases while density decreases, ever so slightly...

As water freezes its volume will expand and break a sealed copper pipe full of water. Because water is undergoing a phase change into ice/crystalline molecular state.

Experiment with a cylinder of equal percentages water and cooking oil. Lighter/less dense oil will float on top of the water. Put colored ice cubes in and they float but as the ice melts, water droplets form and sink down to join the higher density water already on the bottom.

Density of ice or 0 deg C is approximately .99989 grams/cubic centimeter.
Water at 4 deg C is .99995 gm/cm cubed
