PLASMA: A FOURTH
STATE OF MATTER
PAGE 547
• Plasma is a state of matter that starts as a
gas and then becomes ionized.
• Its properties differ from those of a solid,
liquid, or gas.
• Plasma is created when energy is added
to a gas.
• Plasma is similar to a gas in that it has no
fixed shape, but it is different in that it
conducts electric current and is attracted to
magnetic fields.
