Drain cleaners often produce a great deal of heat as they unclog drains. Is the action of drain cleaners a physical or chemical change? ?

    Chemical. Why did you post this 'chemistry' question in the Religion and Spirituality section?

    Drain cleaners contain sodium hydroxide. The sodium hydroxide reacts with the oil and fats in the drain. The heat is result of this exothermic chemical reaction.

      Crystalline drain cleaner, made of sodium hydroxide,
      generates a lot of heat, just by dissolving in water.
      A simplistic way of seeing this process
      is to call it a physical change,
      but, at a molecular level,
      this is also a hydration reaction
      between the hydroxide and water.

    Chemical changes

    are a subset of physical change.

    A change in free energy

    almost always accompanies

    chemical changes.

    The chemical change produces the heat.
