Exploring Phases of Matter

What are the three main phases of matter?

• quark-gluon plasma

• plasma

• superfluid

• solid, liquid, gas

Describe the characteristics of solids.

• Particles are loosely packed and compressible

• Characteristics of solids include definite shape, definite volume, and closely packed particles.

• Solids can flow like liquids

• Definite shape but variable volume

How do liquids differ from solids?

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

• Liquids have a fixed shape and volume like solids.

• Liquids are always denser than solids.

• Liquids differ from solids in that they have no fixed shape but a definite volume, while solids have both a fixed shape and volume.

What is the phase of matter that has no fixed shape?

• liquid

• solid

• plasma

• gas

What happens to the particles in a gas?

• Particles in a gas vibrate in place without moving freely.

• Particles in a gas are tightly packed together.

• Particles in a gas are fixed in a rigid structure.

• Particles in a gas move freely and are widely spaced apart.

Define the term 'melting'.

• Melting is the process of a solid becoming a gas.

• Melting is the process of gas turning into a liquid.

• Melting is the process of a liquid turning into a solid.

• Melting is the process of a solid turning into a liquid.

What is condensation?

• Condensation is the process of liquid water turning into water vapor.

• Condensation is the freezing of water vapor into ice.

• Condensation is the evaporation of water from surfaces.

• Condensation is the process of water vapor turning into liquid water.

How does temperature affect the state of matter?

• Temperature changes can cause matter to transition between solid, liquid, and gas states.

• All matter remains in a solid state regardless of temperature.

• Temperature changes do not affect the state of matter at all.

• Temperature only affects gases, not solids or liquids.

What is the process of a solid turning directly into a gas called?

• Evaporation

• Condensation

• Sublimation

• Melting

Explain what happens during freezing.

• Freezing occurs when a liquid evaporates into the air.

• Freezing is the process of a solid melting into a liquid.

• Freezing is when a solid turns into a gas due to heat.

• Freezing is the process where a liquid turns into a solid as it loses heat and reaches its freezing point.
