The Three States Of Matter Flashcards
What are the three states of matter?
Solid, liquid, and gas.
Where do melting and freezing occur in terms of temperature?
At the melting point.
Where do boiling and condensing occur in terms of temperature?
At the boiling point.
How are particles represented in the model depicting the three states of matter?
By small solid spheres.
What can particle theory explain regarding changes of state?
It can explain melting, boiling, freezing, and condensing.
What determines the amount of energy needed to change states?
The strength of forces between particles.
How does the strength of forces between particles relate to melting and boiling points?
The stronger the forces, the higher the melting and boiling points.
What skills should students develop related to states of matter and particle theory?
Predicting states at different temperatures, explaining state changes in terms of energy transfers and bonding, recognizing that atoms lack bulk properties, and, in higher tiers, explaining limitations of particle theory in relation to changes of state.
