Video: Freezing and Melting of Water

Introduction

Freezing temperature, the temperature at which a substance turns from liquid to solid, and melting temperature, the temperature at which a substance turns from a solid to a liquid, are characteristic physical properties. In this experiment, the cooling and warming behavior of a familiar substance, water, will be investigated. By examining graphs of the data, the freezing and melting temperatures of water will be determined and compared.

Objectives

In this experiment, you will

  • Collect temperature data during the freezing and melting of water.
  • Analyze graphs to determine the freezing and melting temperatures of water.
  • Determine the relationship between the freezing and melting temperatures of water.
