Final answer:

Physical and chemical changes are distinguishable in chemistry based on whether new substances are formed or if it's a change of state or appearance.


Explanation:

Chemical Change:

  1. A solid melts: Physical change, as the state changes from solid to liquid with no new substances formed.
  2. Sugar dissolves in water: Chemical change, as the sugar molecules disperse in water to form new chemical entities.
  3. A solid sublimes: Physical change, as the solid directly transitions to a gas without forming new substances.
