Please look at this trying to help my brother

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.

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !

age range would be the answer
