Question

which state of matter is characterized by ionized particles, no definite shape or volume, and good electrical conductivity?

plasma
liquid
gas
solid

Explanation:

Analyze the given characteristics

The question asks for a state of matter characterized by:

• Ionized particles (free electrons and ions)
• No definite shape or volume
• Good electrical conductivity

Evaluate the options

• Solid: Definite shape and volume; particles are tightly packed in a fixed lattice.
• Liquid: Definite volume but no definite shape; particles can slide past each other.
• Gas: No definite shape or volume; particles are neutral and widely spaced.
• Plasma: No definite shape or volume; composed of highly energetic, ionized gas particles (ions and free electrons) which allow it to conduct electricity extremely well.

Answer:

• plasma (Correct answer)
• liquid
• gas
• solid
