1 answer

Here are the statements evaluated as true or false:

  1. Changing the size and shapes of pieces of wood would be a chemical change: False (It is a physical change.)
  2. Evaporation is a physical change: True
  3. Sand being washed out to the sea from the beach is a chemical change: False (It is a physical change.)
  4. Combining hydrogen and oxygen to make water is a physical change: False (It is a chemical change.)
  5. When ice cream melts, a chemical change occurs: False (It is a physical change.)
  6. Breaking up concrete is a physical change: True
  7. Acid rain damaging a marble statue is a physical change: False (It involves a chemical change; the marble reacts with acid.)
  8. Burning wood is a physical change: False (It is a chemical change.)
  9. A physical change the makeup of matter is changed: False (In a physical change, the makeup of matter does not change; the substance remains the same.)
