What happens to the molecules in a solid?

• Molecules in a solid have very little movement and are closely packed.

• Molecules in a solid move freely and are widely spaced.

• Molecules in a solid vibrate rapidly and are loosely arranged.

• Molecules in a solid are in a gaseous state and spread out.

What is the main difference between solids and liquids in terms of shape?

• Solids have a fixed shape, while liquids do not.

• Liquids have a fixed shape, while solids do not.

• Both solids and liquids have a fixed shape.

• Solids can change shape, while liquids cannot.

How do gas molecules behave in terms of movement?

• Gas molecules vibrate and move freely at high speeds.

• Gas molecules are stationary and do not move.

• Gas molecules move slowly and in a fixed position.

• Gas molecules only vibrate without any movement.

What is the relationship between pressure and the volume of a gas?

• According to Boyle's Law, as pressure increases, the volume of a gas decreases, and vice versa.

• As pressure increases, the volume of a gas increases, according to Charles's Law.

• Pressure and volume are directly proportional according to Avogadro's principle.

• The volume of a gas remains constant regardless of pressure changes.

Do liquids have a definite shape?

• Yes, liquids have a definite shape.

• No, liquids take the shape of their container.

• Liquids have a fixed volume but no fixed shape.

• Liquids can change shape but not volume.

What is the characteristic of gas molecules compared to solid and liquid molecules?

• Gas molecules are closely packed and vibrate in place.

• Gas molecules are far apart and move freely, while solid and liquid molecules are closer together.

• Gas molecules have a definite shape and volume, unlike solids and liquids.

• Gas molecules are heavier than solid and liquid molecules.

What happens to the volume of a gas when it is compressed?

• The volume of a gas increases.

• The volume of a gas decreases when it is compressed.

• The volume of a gas remains the same.

• The volume of a gas fluctuates randomly.
