Answer

Brief Explanations:

Physical changes involve a change in form or state without altering the chemical composition. Chemical changes result in the formation of new substances with different chemical properties.

  • "Boil" is a physical change as it's a state - change from liquid to gas without a chemical reaction.
  • "Burn" is a chemical change as it involves a reaction with oxygen to produce new substances.
  • "Condense" is a physical change (gas to liquid state - change).
  • "Corrode" is a chemical change as metal reacts with substances in the environment to form new compounds.
  • "Crumple" is a physical change as it only changes the shape of an object.
  • "Crush" is a physical change as it changes the form of a solid without changing its chemical makeup.
  • "Explode" can be a chemical change if it involves a chemical reaction like in an explosive compound.
  • "Ferment" is a chemical change as yeast converts sugars into alcohol and carbon - dioxide.
  • "Freeze" is a physical change (liquid to solid state - change).
  • "Grind" is a physical change as it only changes the particle size of a substance.
  • "Melt" is a physical change (solid to liquid state - change).
  • "Oxidize" is a chemical change as a substance reacts with oxygen.
  • "Rot" is a chemical change as organic matter decomposes through chemical reactions.
  • "Rust" is a chemical change as iron reacts with oxygen and water to form iron oxide.
  • "Tarnish" is a chemical change as a metal reacts with substances in the air to form a new layer on its surface.
  • "Vaporize" is a physical change (liquid to gas state - change).
