Presentation Transcript
Slide1Melting and DissolvingFOSS Kit: Chemical Interactions 8th Grade
Slide2Melting When a substance melts, it changes from a solid to a liquid. Melted particles do not change the composition of the substance.
Slide3Melting Heat is used to change a solid to a liquid. • Heat changes the kinetic energy of the particles of the substance. • When particles have a sufficient level of kinetic energy, the particles start to move over and past one another as liquid.
Slide4Dissolving Dissolving is when a solid substance is placed in water, or another liquid, and particles of the solid substance break away and move into the liquid.
Slide5Dissolving The liquid with the substance dissolved in it is a solution . • A solution of a substance is made of particles of that substance mixed uniformly with particles of the liquid in which it is dissolved.
