Question

directions:

1. add or remove heat to change the temperature of neon.
2. observe how changing temperature affects the particle

motion and physical state of neon.
select the correct statement(s).
the particles of neon as a solid move faster than when
it is a liquid or a gas.
raising the temperature increases the kinetic energy of
the particles of neon.
lowering the temperature increases the kinetic energy
of the particles of neon.
the temperature of neon as a solid is lower than when
it is a liquid or a gas.
the particles of neon move the fastest when it is a gas.
this is because they are at the highest temperature.
they also have the most kinetic energy.

Explanation:

• "Lowering the temperature increases the kinetic energy of the particles of neon." is incorrect. Kinetic energy is related to temperature. As temperature decreases, kinetic energy decreases.
• "The particles of neon as a solid move faster than when it is a liquid or a gas." is incorrect. In solids, particles have the least movement (vibrate in fixed positions), while in gases, they move the fastest.
• "The temperature of neon as a solid is lower than when it is a liquid or a gas." is correct. Solids generally have lower temperatures (less kinetic energy of particles) compared to liquids and gases (for the same substance under normal conditions).
• "The particles of neon move the fastest when it is a gas." is correct. In the gaseous state, particles have the highest kinetic energy and move the fastest among the three states (solid, liquid, gas).
• "This is because they are at the highest temperature." is correct. High - temperature means high - kinetic energy. Gaseous neon (when compared to its solid and liquid states) has the highest temperature (under normal phase - change scenarios where heating leads to phase change from solid to liquid to gas), so particles have the most kinetic energy.

Answer:

The correct statements are: "The temperature of neon as a solid is lower than when it is a liquid or a gas.", "The particles of neon move the fastest when it is a gas.", "This is because they are at the highest temperature."
