Question
Understanding that the density of ice and water change with temperature, what two interesting facts can be revealed from such knowledge?ResponsesA Water’s maximum density is at 0 °C.Water’s maximum density is at 0 °C.B Water’s maximum density is at 4 °C.Water’s maximum density is at 4 °C.C The density of ice is significantly greater than water.The density of ice is significantly greater than water.D The density of water is significantly greater than ice.
Solution
The two interesting facts that can be revealed from the knowledge that the density of ice and water change with temperature are:
B. Water’s maximum density is at 4 °C. This is unique because unlike most substances, water does not continuously become denser as it cools (down to its freezing point). Instead, it reaches its maximum density at 4 °C, and then becomes less dense as it cools further.
D. The density of water is significantly greater than ice. This is why ice floats on water. When water freezes into ice, it expands and its density decreases. This is also somewhat unusual, as most substances are denser in their solid form than in their liquid form.

Liquid water is more dense than ice becauseSelect one:a.A liquid H2O molecule has more mass than an ice H2O molecule.b.A chemical change occurs when ice melts that causes the mass of water to increasec.there are a greater number of H2O molecules per unit of volume in liquid water than ice.d.When ice melts there is an increase in the amount of water molecule
Density of ice is ρ and that of water is σ. What will be the decrease in volume when a mass M of ice melts
The additional heat causes the kinetic energy of some of the ice molecules to so they can more readily undergo the phase change to liquid. Therefore, the temperature of the ice remains constant. Since some of the ice changes to liquid water, the amount of ice .
