Question 12 of 13intermediate✨ CreateShort Answer3 marks

Pretend to be particles of solids, liquids, and gases, at different temperatures—create and perform a role-play/dance showing particles in motion.

Correct Answer

For solids: Students should stand close together in fixed positions, swaying slightly to represent vibration. When 'heated', they should sway more vigorously but remain in place.

For liquids: Students should stand slightly apart, moving around slowly within a limited area, able to slide past each other. When 'heated', movement becomes faster.

For gases: Students should spread far apart, running freely in all directions. When 'heated', movement becomes even faster and more energetic.

Explanation

The chapter explains that particles in solids can only vibrate about fixed positions, particles in liquids can move within limited space, and particles in gases move freely in all directions. Heating increases thermal energy and particle movement in all states.

Solution Steps

  1. Particles in solids can only vibrate about fixed positions

  2. Particles in liquids can move within limited space

  3. Particles in gases move freely in all directions

  4. Heating increases thermal energy and particle movement in all states
