Learning checkpoint 1-1(M2L1)

Which of the following best describes the arrangement of particles in a gas?

• Tightly packed in a fixed position
• Loosely arranged with some movement
• Widely spaced with rapid, random motion
• Arranged in a repeating crystal structure

Which state of matter has the most rigid and defined shape?

• Solid
• Liquid
• Gas
• Plasma

What is the primary difference between physical and chemical properties?

• Physical properties can be observed without changing the substance's composition, while chemical properties involve changes in composition
• Chemical properties can be observed without changing the substance's composition, while physical properties involve changes in composition
• Physical properties only apply to solids, while chemical properties apply to all states of matter
• There is no difference between physical and chemical properties

Which of the following is an example of an intensive property?

• Mass
• Volume
• Melting point
• Total energy

What characteristic distinguishes an extensive property from an intensive property?

• Extensive properties depend on the amount of matter, while intensive properties do not
• Intensive properties depend on the amount of matter, while extensive properties do not
• Extensive properties only apply to gases, while intensive properties apply to all states of matter
• There is no difference between extensive and intensive properties

Which state of matter has particles that vibrate in fixed positions?

• Solid

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

• Solid particles are in constant motion, while liquid particles are stationary
• Liquid particles have more freedom of movement than solid particles
• Solid particles are more widely spaced than liquid particles
• There is no difference in particle arrangement between solids and liquids

What characteristic of gases allows them to expand to fill their container?
