Matter and its Properties

What is matter?

• Matter is a type of energy.
• Matter is anything that has mass and occupies space.
• Matter is only found in solid form.
• Matter is a concept that cannot be measured.

Which of the following is correct about solids?

• Solids have a definite shape and volume.
• Solids are always transparent and allow light to pass through.
• Solids have a variable shape but a fixed volume.
• Solids can flow and take the shape of their container.

Which of the following correctly describes a matter in liquid state?

• Matter in liquid state has a definite volume but no definite shape.
• Matter in liquid state has a definite shape and volume.
• Matter in liquid state has a definite shape but no definite volume.
• Matter in liquid state has no definite volume and no definite shape.

Why are the particles of gas far from each other?

• Gas particles are far from each other due to their high kinetic energy and rapid movement.
• Gas particles are attracted to each other by strong forces.
• Gas particles are stationary and do not move.
• Gas particles are tightly packed due to low temperature.

What makes liquids different from gas?

• Gases have a definite volume and take the shape of their container.
• Liquids have a definite volume and take the shape of their container, while gases have neither a definite volume nor shape.
• Liquids have no volume and fill their container completely.
• Liquids can be compressed easily like gases.

What happens to the particles of gas when the temperature is increased?

• The particles of gas expand but do not change speed.
• The particles of gas move faster and collide more frequently.
• The particles of gas become solid and stop moving.
• The particles of gas lose energy and slow down.

Which of the following correct about the densities of the states of matter?

• Solids have the highest density, followed by liquids, and gases have the lowest density.
• Solids and liquids have the same density, while gases have a higher density.
• Liquids have the highest density, followed by gases, and solids have the lowest density.
• Gases have the highest density, followed by solids, and liquids have the lowest density.

Why do liquids have a higher density than gases?

• Liquids have a higher density than gases because their molecules are more closely packed together.
• Liquids are denser because they are colder than gases.
• Gases have a higher density due to their larger molecular size.
• Liquids are less dense because they contain more air.

Which of the following is true about the kinetic particles of solids, liquids and gases?

• In solids, particles vibrate in fixed positions; in liquids, they move more freely; in gases, they move rapidly and are far apart.
• In solids, particles move freely; in liquids, they vibrate in fixed positions; in gases, they are closely packed.
• In solids, particles move rapidly; in liquids, they are tightly packed; in gases, they vibrate in place.
• In solids, particles are far apart; in liquids, they vibrate rapidly; in gases, they are stationary.

Which of the following correctly describes the compressibility of the states of matter?

• Gases are the least compressible, liquids are highly compressible, and solids are less compressible.
• Gases are highly compressible, liquids are less compressible, and solids are the least compressible.
• Solids are highly compressible, liquids are the least compressible, and gases are less compressible.
• Liquids are more compressible than gases, and solids are equally compressible as liquids.
