¿Qué es un sólido?

The video explains the characteristics of solid materials, highlighting their fixed shape and inability to change volume without external forces. Solids have tightly packed molecules, making them incompressible. Examples like pizza dough illustrate how solids can change shape but not volume. The video contrasts solids with gases and liquids, emphasizing the unique properties of solids.

What characteristic defines a material as a solid?

• It can change shape easily.

• It flows like a liquid.

• It has a fixed shape under normal conditions.

• It can be compressed into a smaller volume.

Which of the following actions can change the shape of a solid?

• Exposing it to air.

• Placing it in water.

• Applying heat or force.

• Leaving it in a room.

Why can't solids change their volume?

• They are lighter than gases.

• They are always in motion.

• They are made of tightly packed molecules.

• They have a fixed shape.

What happens to the volume of pizza dough when it is rolled?

• It remains the same.

• It disappears.

• It decreases.

• It increases.

How can the volume of a solid be reduced?

• By eating it.

• By freezing it.

• By heating it.

• By compressing it.
