Exploring States of Matter CBSC 5 GRADE

What are the main characteristics of solids?

• Definite shape but variable volume

• Definite shape and volume, incompressibility, high density, and fixed particle arrangement.

• Random particle arrangement

• Low density and fluidity

How do particles in a liquid behave compared to solids?

• Particles in a liquid cannot move and are fixed in place.

• Particles in a liquid are less tightly packed than in solids and can move freely, allowing liquids to flow.

• Particles in a liquid are more tightly packed than in solids.

• Particles in a liquid behave like gas particles, expanding to fill their container.

What is the shape of a solid object?

• Fluid-like shape with no volume

• Definite shape and volume

• No definite shape, but definite volume

• Shape changes with temperature

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

• The volume of a gas remains constant when it is heated.

• The volume of a gas fluctuates randomly when it is heated.

• The volume of a gas increases when it is heated.

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

Can liquids be compressed easily? Why or why not?

• No, liquids cannot be compressed easily.

• Liquids can be compressed as easily as gases.

• Yes, liquids can be compressed easily due to their molecular structure.

• Liquids can be compressed under extreme pressure only.

What is the difference between a gas and a liquid in terms of particle arrangement?

• Gas particles are far apart and move freely, while liquid particles are closer together and can slide past each other.

• Gas particles are tightly packed and vibrate in place.

• Liquid particles are far apart and move freely.

• Gas particles have a fixed shape and volume.

What is the term for the change from solid to liquid?

• Melting

• Sublimation

• Condensation

• Freezing

How does pressure affect the behavior of gases?

• Pressure has no effect on gas behavior.

• Increased pressure increases volume and temperature.

• Pressure affects gases by changing their volume and temperature; increased pressure decreases volume, while decreased pressure allows expansion.

• Decreased pressure causes gases to become denser.

What is an example of a substance that can exist in all three states of matter?

• Steam

• Water

• Ice

• Carbon Dioxide

What happens to the temperature of a gas when it expands?

• The temperature of a gas always increases when it expands.

• The temperature of a gas remains constant during expansion.

• The temperature of a gas cannot change during any type of expansion.

• The temperature of a gas can decrease when it expands, depending on the conditions of the expansion.
