The correct answer is True
Step-by-step explanation:
Solids are one of the four states of matter that exists in the universe along with plasma, liquids, and gases. Different to other states of matter, all solids have a defined shape and volume, this can be explained as the atoms in solids do not change their position but instead, are part of a tight structure or regular pattern that does not naturally change or allows the atoms to move freely as in the case of gases. Additionally, in atoms of solids, the only motion that can take place is vibration but in natural conditions, the shape and volume remain the same. Thus, it is true in solids, atoms are tightly locked and do not change position.
