Question

Mary and Ron are discussing the properties of water. Mary says that when water freezes, it becomes less dense than liquid water. Ron says it becomes more dense. Who is correct and why?
Ron, because ice molecules are smaller than liquid water molecules

Ron because ice sinks in liquid water

Mary, because ice molecules are larger than liquid water molecules

Mary, because lakes and ponds freeze at the bottom first

Answer 1

Answer:

Mary, because ice molecules are larger than liquid water molecules

Explanation:

Answer 2

Mary, because ice molecules are larger than liquid water molecules

Explanation:

Mary is correct because when water freezes, it becomes less dense than normal liquid water. Ice molecules are larger than liquid water molecules because they are less packed.

• Density is a function of mass and volume of a body:

              Density = $\frac{mass}{volume}$

• Mass is the amount of matter contained in substance.
• Volume is the space occupied by a body.
• When a substance is frozen, it expands. This implies that the volume increases considerably.
• Since mass stays the same but the volume changes for ice, it will become less packed.
• The density of ice is therefore less compared to that of water.
• So Mary is very correct.
