DOK Level 1: Recall

A block of ice is placed in a warm room. Describe the changes in particle motion and state as it melts.

• Particles slow down and the ice becomes colder

• Particles speed up and the ice becomes a liquid

• Particles stop moving and the ice remains solid

• Particles move in a circular motion and the ice evaporates

DOK Level 2: Skill/Concept

Evaluate the impact of removing thermal energy from a gas on its particle motion and state.

• Particles speed up and the gas becomes a liquid

• Particles slow down and the gas becomes a liquid

• Particles stop moving and the gas remains a gas

• Particles move in a circular motion and the gas becomes a solid
