검증된 단계별 안내1
Understand the states of matter: solid, liquid, gas, and plasma. Each state has distinct characteristics related to shape and volume.
Recall that a solid has a definite shape and definite volume, meaning it maintains its shape without needing a container.
Recognize that a liquid has a definite volume but takes the shape of its container, so it does not have a definite shape.
Know that a gas has neither definite shape nor definite volume, expanding to fill any container.
Since gold has a definite shape and definite volume in its natural state, it must be a solid.
