  • This state of matter has a stable volume, fixed shape, and is not compressible.
    Solid
  • The change from liquid to solid is known as
    Solidification
  • What is the formula for density?
    d=m/v
  • This state of matter has a stable volume, unfixed shape, and is not compressible
    Liquid
  • This state of matter has a unstable volume, unstable shape, and is compressible
    Gas
  • The temperature at which a liquid transforms into a gas is
    Boiling point
  • The change from gas to liquid is known as
    Condensation or liquefication
  • True or false: 1kg of iron is more dense than 10g of iron. Explain
    False. Density is an intensive property and doesnt change based off of the quantity of a substance.
  • The change from solid to liquid is known as
    Melting
  • What is buoyancy and how is it related to density?
    Buoyancy is the ability for a substance to float. Density determines buoyancy.
  • How do you determine the volume of an irregular solid?
    Liquid displacement
  • A __________ change occurs when a substance is cooled
    regressive
  • The amount of matter in a substance is
    Mass
  • True or false: When water is cooled and becomes ice, it contracts, decreasing its volume.
    False.
  • A _________ change occurs when heat is applied.
    progressive
  • When a substance is cooled, it ______, _______ its volume.
    contracts, decreasing
  • The temperature at which a solid transforms to a liquid is
    Melting Point
  • When a substance is heated, it ___________, __________ its volume
    expands, increasing
  • Which is not a unit used to measure volume? Liter, kilogram, cubic meter, milliliter
    kilogram
  • The space an object occupies is
    Volume
