Which statement correctly describes plasma?

Which statement correctly describes plasma?

• A. A solid with a definite shape
• B. A liquid with flowing particles
• C. Matter containing positively and negatively charged particles at very high temperatures
• D. A gas with no definite shape

Answer: (C)

Plasma is a state of matter where atoms are so energized that electrons are stripped away, leaving a mix of positively charged ions and free electrons. Because of these charges, plasma can conduct electricity and respond to magnetic fields, even though it often fills space like a gas. The description that mentions positively and negatively charged particles at very high temperatures best captures this ionized nature. Solids have a definite shape, so that option isn’t right. A description of a liquid implies flowing particles but not ionization. A plain gas describes lack of definite shape but doesn’t include the charged particles that define plasma.
