Quiz 3.2 Changes of state

Read the following: "In this state of matter, particles are closely packed in a regular pattern. They vibrate in place but do not change position. The substance has a definite shape and volume." Which state of matter does this describe?

• Solid

• Liquid

• Gas

• Plasma

Read the following: "When a substance changes from a gas to a liquid, it is known as condensation. This change occurs when particles lose energy and move closer together.” Which process involves the opposite change, where a liquid becomes a gas?"

• Sublimation

• Melting

• Evaporation

• Deposition

Read the following: "Particles in this state of matter are widely spaced and move freely. They take the shape and volume of their container. This state of matter is compressible and has the highest energy." Which state of matter fits this description?

• Solid

• Liquid

• Gas

• Plasma

Read the following: "____ is a high-energy state of matter in which particles have lost their electrons. This state of matter is commonly found in stars and lightning.” Which state of matter completes the blank?

• Solid

• Liquid

• Gas

• Plasma

Read the following: "Diffusion rate refers to the speed at which particles of a substance spread out to fill a space.” In which state of matter is diffusion most rapid due to particles having high kinetic energy?

• Solid

• Liquid

• Gas

• Water

Read the following: "____ determines the strength of attraction (or repulsion) between particles in a substance. In solids, it is strong, while in gases, it is very weak.” What property completes the blank?

• Fluidity

• Density

• Interparticle force

• Compressibility

Liquid nitrogen was poured into the glass. What change of state is taking place in the cup?

• Sublimation

• Condensation

• Evaporation

• Melting
