Answer

Brief Explanations:

  1. Changing size and shape of wood is a physical change as no new substance is formed. So it's False.
  2. In a physical change, the makeup of matter remains the same. So it's False.
  3. Evaporation is when liquid water turns to gas, which is a correct description. So it's True.
  4. Evaporation is a physical change as it only changes the state of water. So it's True.
  5. Burning wood forms new substances like ash and carbon - dioxide, so it's a chemical change, not physical. So it's False.
  6. Combining hydrogen and oxygen to make water is a chemical reaction forming a new substance. So it's False.
  7. Breaking up concrete only changes its physical form, no new substances are formed. So it's True.
  8. Sand being washed out to sea is a physical movement, no new substances are formed. So it's False.
  9. When ice - cream melts, it's a physical change as only the state changes. So it's False.
  10. Acid rain reacting with marble (calcium carbonate) forms new substances, so it's a chemical change. So it's False.
