1.1 States of Matter Quiz (Chem 0620)

What is a characteristic property of solids?

• Fixed volume and shape

• Random particle arrangement

• High compressibility

• Ability to flow

In solids, particles are:

• Densely packed and regularly arranged

• Randomly arranged and far apart

• Moving quickly in all directions

• Arranged loosely in a fixed pattern

What is a characteristic of liquids?

• Fixed volume and fixed shape

• No fixed volume, but a fixed shape

• Fixed volume, but adopts the shape of the container

• Very low density compared to solids

The particles in liquids:

• Are packed closely and vibrate in place

• Move freely and fill any available space

• Slide past each other, allowing the liquid to flow

• Remain stationary in a random arrangement

Which of the following is true for gases?

• They have a fixed volume but no fixed shape

• Particles are very close together

• Gases are highly compressible

• They have high density compared to liquids

In gases, the particles:

• Vibrate in place

• Move randomly and quickly in all directions

• Are packed tightly together

• Slide past one another

Which property distinguishes gases from solids and liquids?

• High density

• Random particle movement

• Compressibility

• Fixed shape

During melting, a solid becomes a liquid because:

• Particles lose kinetic energy

• Particles gain kinetic energy and can move past each other

• The solid's particles become tightly packed

• The liquid's particles freeze in position

Which process describes the change from liquid to gas?

• Condensation

• Freezing

• Evaporation or boiling

• Deposition

What happens during condensation?

• Gas particles lose energy and come closer together

• Liquid particles move faster and spread apart

• Solid particles gain kinetic energy

• Gas particles move faster and spread apart
