Exploring Solids, Liquids, and Gases: Solids

The video tutorial explains the properties of solids, highlighting that they have a definite shape and volume. It provides examples such as books and rocks, and describes how particles in solids are tightly packed and move slowly. The tutorial also discusses water's solid form, ice, and how its particles behave when frozen.

What characteristic of solids is highlighted by their ability to maintain a specific shape?

• They are flexible.

• They have a definite shape.

• They can change volume easily.

• They are transparent.

Which of the following is NOT an example of a solid?

• Water vapor

• Rock

• Plate

• Book

How are particles arranged in solids?

• Tightly packed and slow-moving

• Loosely packed and fast-moving

• Freely moving and widely spaced

• Randomly scattered and stationary

What happens to water when it freezes?

• It becomes a gas.

• It turns into ice.

• It evaporates.

• It remains a liquid.

In the solid form of water, how do the particles behave?

• They are stationary.

• They move rapidly.

• They move freely.

• They move very slowly.
