Changing States of Matter
Changing states of matter occur when matter loses or absorbs energy. When a substance absorbs energy the atoms and molecules move more rapidly and this increased kinetic energy pushes particles far enough that they change form. These concepts were explained with a hands-on activity.
Class VI and VII
