Good morning teacher and classmates today we are going to present you about . Our group is : Sofía nuñes, Grecia Mejía, Diana López, Isabella Castillo, Paola Cabrera, Montserrat Barrera , Adriana Chicas, Lourdes Doratt. Title Slide: Phase Changes of Matter ⸻ Slide 1: What is a Phase Change? • A phase change is the physical process of transitioning from one state of matter to another (solid, liquid, or gas). • It requires a sufficient gain or loss of energy, usually in the form of heat. ⸻ Slide 2: Examples of Phase Changes • A liquid that absorbs enough energy becomes a gas (evaporation). • A liquid that loses enough energy becomes a solid (freezing). ⸻ Slide 3: Energy and Phase Changes • Absorbing Energy: Solid to liquid, liquid to gas, solid to gas. • These transitions require heat energy to be absorbed. • Releasing Energy: Liquid to solid, gas to liquid, gas to solid. • These transitions release heat energy. ⸻ Slide 5: Summary • Phase changes involve energy transfer. • Heat absorbed = particles move faster and change to a higher-energy state. • Heat released = particles slow down and change to a lower-energy state. Thanks.
