Calculating Volume Change of Water When it Freezes

Introduction

Water is a fundamental substance in our daily lives, existing in various states depending on temperature. In this scenario, we will explore how the volume of water changes when it freezes from its liquid state.

Problem Statement

At 25 °C, a bottle contains 2.00 L of water in its liquid state. What is the volume of the water after it freezes (at 0 °C)? The densities of liquid water and ice are 0.997 g/mL and 0.917 g/mL, respectively.

Solution

Answer: 2.175 L Explanation: Temperature (T) = 25 degrees Celsius Volume of water (V) = 2 L = 2000 mL Density of water = 0.997 g/mL Density of ice = 0.917 g/mL We can calculate the mass of the water and then use it to determine the volume when it freezes to ice, as the mass remains constant despite the change in state. Mass of water = Volume x Density Mass of water = 2000 mL x 0.997 g/mL = 1994 g Volume of ice = Mass / Density Volume of ice = 1994 g / 0.917 g/mL = 2174.5 mL = 2.175 L

What is the volume of the water after it freezes from its liquid state?

The volume of the water after it freezes is 2.175 L.
