Changes of State and Density

• What state of matter are solids considered to be?

  The most dense state
• Why are solids the most dense state of matter?

  Particles are tightly packed in solids
• How are liquids arranged compared to solids?

  Less dense than solids
• What does a disordered arrangement of particles in liquids mean?

  Particles are less tightly packed than in solids
• How do gases compare in density to solids and liquids?

  Very low in density
• What is the implication of having fewer particles in a given volume for gases?

  They are less dense than solids and liquids
• Are there exceptions to the density pattern among states of matter?

  Yes, there are some exceptions
• Why is liquid water denser than solid ice?

  Due to the way ice expands when frozen
• How does the expansion of water when it freezes affect its density?

  It causes ice to be less dense than water
