Answer:
Solid: State of matter with definite shape.
Gas: State of matter with particles very far apart.
1 or 3: Arrows that show particles getting closer together.
2 or 4: Arrows that show particles gaining energy.
Gas: State of matter that will fill any container.
Liquid: Sate of matter with definite volume but not shape.
Solid: State of mater with least amount of kinetic energy.
Explanation:
Solids atoms are very closely packed and have little or no movement at all. When a solid object is heated, it's atoms gain kinetic energy and convert into liquid form. The liquid form has a definite volume but not a definite shape. When liquids are heated then gain kinetic energy and convert into a gas. Gas neither have a definite shape nor a definite volume.
