The three primаry phаses оf оrdinаry matter are sоlids, liquids and gasses. 1)_____________________ are characterized by having their atoms located in fixed positions; in the 2)_______________________ phase, particles experience significant attraction to one another and are located close together, but not in fixed positions such that they can slide past one another; in the 3)__________________ phase, particles do not experience enough attraction to one another to stay together, and move independently with little interaction. Transitions between phases of matter are often possible with changes in 4)_________________. As heat energy is added, particle movement increases, and as attractive forces are overcome, solids can transition to liquids and liquids to gasses. The stronger the attractive interactions are, the more energy is required, resulting in higher 5)____________________________ points.
