VERIFIED QUESTIONS AND CORRECT
ANSWERS
●● Solid
Answer: A state of matter characterized by structural rigidity and
resistance to changes in shape or volume.
●● Liquid
Answer: A state of matter that has a definite volume but no fixed shape,
allowing it to flow freely.
●● Gas
Answer: A state of matter without a definite shape or volume, where
molecules move freely and expand to fill their container.
●● Plasma
Answer: A state of matter similar to gas but consisting of free ions and
electrons which occur at high temperatures or when subjected to electric
fields.
●● Atoms
, Answer: The smallest units of matter that retain the properties of an
element, consisting of a nucleus surrounded by electrons.
●● Protons
Answer: Positively charged subatomic particles found in the nucleus of
an atom.
●● Electrons
Answer: Negatively charged subatomic particles that orbit the nucleus of
an atom.
●● Neutrons
Answer: Neutral subatomic particles found in the nucleus of an atom.
●● Nucleus
Answer: The central part of an atom, containing protons and neutrons.
●● Conductivity
Answer: The ability of a material to conduct electricity or heat.
●● Hardness
