Reggie puts a beaker of ice and water on a hot plate he observed the ice slowly melt as shown in the diagram below after a few minutes only liquid water is left in the beaker eventually the water becomes hot enough to boil. the liquid water changes to water vapor which is a gas
. This process of a substance changing from a solid to a liquid to a gas is called phase changes.
As the ice melted, it went through a phase change from a solid to a liquid. When the liquid water was heated and boiled, it went through another phase change from a liquid to a gas.
This process demonstrates how temperature can affect the physical state of a substance, changing it from one phase to another. By carefully controlling the temperature and observing the changes, scientists can learn more about the properties and behavior of different substances.
