CHANGES An introduction to different phase OF STATE changes of matter and their examples Recall: States of Matter SOLID LIQUID GAS Is it possible for a solid to turn into liquid or gas? How does it occur? Learning Outcomes Compare and Explain how a Cite a few contrast the six change of state applications of common changes of occurs. change of state. state. Change of State occurs when matter changes from one state to another It does not involve It is a physical It occurs when heat is It is reversible. temperature change. removed or added. changes. Types of Changes of State MELTING FREEZING solid changes into liquid changes into a heat is added heat is removed liquid solid a block of butter melting water turning into ice Gallium: A Metal That Melts Gallium in Your Hand! Ga Gallium is a soft, silvery-white metal. It is solid at room temperature but can turn into liquid in your hand. This is because of its low melting point at 85.6°F (29.8°C). Types of Changes of State EVAPORATION CONDENSATION liquid changes into gas changes into heat is added heat is removed gas liquid wet clothes drying in the sun cloud formation Types of Changes of State SUBLIMATION DEPOSITION solid changes directly gas changes into a heat is added heat is removed into gas solid dry ice formation of frost (solid form of carbon dioxide) What's That State Again? CHANGE OF STATE occurs when matter changes from one state to another TYPES OF CHANGES OF STATE freezing melting evaporation condensation sublimation deposition What Is the Most Interesting Property of Water for You? Explain how this specific property makes life possible on Earth. Find a research buddy and share an answer or two next meeting. Questions?
