Question

you have learned about how particles in solids, liquids, and gases behave as thermal energy increases. click the blue words to describe how particles in a substance behave as thermal energy decreases.
when a gas is cooled, the particles begin to move more slowly. when the temperature drops below the melting point, the substances particles have condensed and formed a liquid. if the liquid is cooled down even more, the amount of thermal energy in the particles will decrease, and the liquids temperature will continue to decrease. eventually, the substance will freeze and form a solid. if the temperature continues to increase, the particles in the solid will move around one another more slowly.

Explanation:

The task is to select blue words that correctly describe particle behavior as thermal energy decreases.

1. "slowly": When thermal energy drops, gas particles move slower (correct for cooling gas).
2. "melting point" is incorrect; we use boiling point for gas-to-liquid condensation. The correct term here should be "condensation point", but since we only use given blue words, we exclude this.
3. "decrease": Cooling a liquid reduces particle thermal energy (correct).
4. "increase" is incorrect; thermal energy decreases as temperature drops, so we exclude this.
5. "move around one another more slowly": As a liquid cools to a solid, particle motion slows (correct for decreasing thermal energy).

Answer:

The correct blue words to select are: slowly, decrease, move around one another more slowly
