Exploring States of Matter

What are the three primary states of matter?

• plasma, vapor, foam

• gas, liquid, crystal

• solid, liquid, plasma

• solid, liquid, gas

Describe the arrangement of particles in a solid.

• Particles in a solid are closely packed in a fixed arrangement, vibrating in place.

• Particles in a solid are loosely arranged and can move freely.

• Particles in a solid are spread out and can flow like a liquid.

• Particles in a solid are arranged in a random pattern with large gaps.

How do liquids differ from solids in terms of shape?

• Liquids have no fixed shape and conform to the shape of their container, whereas solids have a definite shape.

• Liquids are always denser than solids.

• Solids can flow and take the shape of their container.

• Liquids have a definite shape like solids.

What is the effect of temperature on gas volume?

• Temperature has no effect on gas volume.

• The volume of a gas increases with an increase in temperature.

• The volume of a gas decreases with an increase in temperature.

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

List two properties that are common to all gases.

• Gases have a definite volume.

• Gases are incompressible.

• Gases can only exist in solid form.

• 1. Gases have no fixed shape. 2. Gases expand to fill their container.

Explain how solids maintain their shape.

• Solids maintain their shape because they are always in motion.

• Solids maintain their shape by expanding to fill their container.

• Solids can change shape easily due to weak intermolecular forces.

• Solids maintain their shape because their particles are tightly packed and held together by strong intermolecular forces.

What is a practical application of liquids in everyday life?

• Cleaning products like detergents and soaps.

• Fuel for vehicles such as gasoline and diesel.

• Cooking liquids such as water, oil, and broth.

• Beverages like soda and juice.

How does the density of a gas compare to that of a solid?

• The density of a gas varies greatly but is generally similar to that of a solid.

• The density of a gas is equal to that of a solid.

• The density of a gas is much lower than that of a solid.

• The density of a gas is higher than that of a solid.
