Phase Changes in Matter
Matter can exist in three phases: solid, liquid, and gas. Each phase has its own unique characteristics and properties.
- Solidshave a fixed shape and volume. The particles in a solid are tightly packed together and do not move very much.
- Liquidshave a fixed volume but no fixed shape. The particles in a liquid are closely packed together but can move around each other.
- Gaseshave no fixed shape or volume. The particles in a gas are far apart and move around freely.
Everyday examples of substances in each phase include:
- Solids:ice, wood, metal
- Liquids:water, milk, oil
- Gases:air, helium, oxygen
Temperature plays an important role in phase changes. When a substance is heated, its temperature increases and its particles move faster. This can cause the substance to change from one phase to another. For example, when ice is heated, it melts and turns into water.
When water is heated, it boils and turns into steam.
Gizmo Simulation: Student Exploration Phase Changes, Student exploration phase changes gizmo answers
The Gizmo simulation is a tool that allows students to explore phase changes. The simulation includes a variety of substances, and students can change the temperature of the substance to see how it changes phase.The Gizmo simulation can be used to:
- Investigate the three phases of matter and their properties.
- Explore the role of temperature in phase changes.
- Predict the phase changes that will occur when a substance is heated or cooled.
To run the simulation, students first select a substance. They can then use the controls to change the temperature of the substance. The simulation will show the substance’s phase and its temperature on a graph.Students can use the simulation to answer questions such as:
- What happens to the phase of a substance when its temperature is increased?
- What happens to the temperature of a substance when it changes phase?
- What is the relationship between the temperature of a substance and its phase?
Heating and Cooling Curves
A heating curve shows the temperature of a substance as it is heated. A cooling curve shows the temperature of a substance as it is cooled.The heating curve and cooling curve of a substance can be used to identify phase changes.
When a substance changes phase, there is a change in the slope of the heating curve or cooling curve.The following are the stages of a heating curve:
- Solid phase:The temperature of the substance increases as it is heated. The slope of the heating curve is constant.
- Melting point:The temperature of the substance remains constant as it melts. The slope of the heating curve is zero.
- Liquid phase:The temperature of the substance increases as it is heated. The slope of the heating curve is constant.
- Boiling point:The temperature of the substance remains constant as it boils. The slope of the heating curve is zero.
- Gas phase:The temperature of the substance increases as it is heated. The slope of the heating curve is constant.
The cooling curve of a substance is similar to the heating curve, but in reverse order.
Applications of Phase Changes
Phase changes have a wide range of applications in everyday life. Some examples include:
- Refrigeration:Refrigerators use the phase change of water to remove heat from food. The water in the refrigerator evaporates, which cools the food. The water vapor then condenses on the coils of the refrigerator, which releases heat. This heat is then transferred to the outside of the refrigerator.
- Air conditioning:Air conditioners use the phase change of water to cool air. The water in the air conditioner evaporates, which cools the air. The water vapor then condenses on the coils of the air conditioner, which releases heat. This heat is then transferred to the outside of the air conditioner.
- Power plants:Power plants use the phase change of water to generate electricity. The water in the power plant is heated until it boils. The steam from the boiling water is then used to drive a turbine, which generates electricity.
