Water has a density of 0.997 g/cm³ at 25 °C; ice has a density of 0.917 g/cm³ at -10 °C. (a) If a soft-drink bottle whose volume is 1.50 L is completely filled with water and then frozen to -10 °C, what volume does the ice occupy? (b) Can the ice be contained within the bottle?

Key Concepts

Density

Density is defined as mass per unit volume and is a critical property of substances. It is calculated using the formula density = mass/volume. In this question, the densities of water and ice are provided, which are essential for determining how the volume changes when water freezes. Understanding density helps explain why ice floats on water, as it is less dense than liquid water.

Volume and Volume Displacement

Volume refers to the amount of space an object occupies, measured in liters or cubic centimeters. When a substance changes state, such as water freezing into ice, its volume can change due to differences in density. The concept of volume displacement is important here, as the volume of ice formed from the water will determine whether it can fit back into the original container after freezing.

Phase Changes

Phase changes refer to the transitions between solid, liquid, and gas states of matter. When water freezes, it undergoes a phase change from liquid to solid, which involves energy transfer and changes in molecular arrangement. Understanding phase changes is crucial for predicting how the properties of substances, such as volume and density, will alter during the freezing process.
