Question

suppose you were given a substance and asked to determine whether it was a plasma. what characteristics would be true of the substance for it to be a plasma? check all that apply. the particles in the substance would collide more often. the particles in the substance would have high kinetic energy. the particles in the substance would be close to each other. the substance would have a fixed shape and volume. the substance would be composed of ionized particles. retry

Explanation:

To determine if a substance is plasma, recall plasma properties:

• Plasma has ionized particles (charged, like in stars or neon signs).
• Particles have high kinetic energy (due to high temperature, leading to frequent collisions).
• Plasma does not have a fixed shape/volume (like gases, it expands to fill its container) and particles are not close (unlike solids/liquids; plasma is like a highly energized gas).

So:

• "Particles collide more often": True (high KE → frequent collisions).
• "Particles have high kinetic energy": True (plasma is high-energy state).
• "Particles close to each other": False (plasma is like gas, particles are far).
• "Fixed shape/volume": False (plasma, like gas, has no fixed shape/volume).
• "Composed of ionized particles": True (defining feature of plasma).

Answer:

• The particles in the substance would collide more often.
• The particles in the substance would have high kinetic energy.
• The substance would be composed of ionized particles.
