Solid

The transcript explains that solids have a rigid structure with a defined shape. Particles within a solid can vibrate due to thermal energy but remain in fixed positions relative to each other.

What characteristic of solids is due to the tight arrangement of their particles?

• High compressibility

• Defined shape

• Ability to flow

• Random structure

What causes particles in a solid to vibrate?

• Magnetic fields

• Thermal energy

• Electric currents

• Gravitational pull

Despite their vibration, what do particles in a solid maintain?

• Random movement

• Fluidity

• Fixed positions

• High speed

Which of the following is NOT a property of particles in a solid?

• They can move freely

• They can vibrate

• They are in fixed positions

• They have a defined shape

How do particles in a solid differ from those in a liquid?

• They have more energy

• They are more spread out

• They move more freely

• They are in fixed positions
