Blending a smoothie, for example, involves two physical changes: the change in shape of each fruit and the mixing together of many different pieces of fruit. But the outcome of this blending is not at all the same as the original fruit. So can you justify why it cannot be termed as a chemical change? [3 MARKS]

• We know that blending a smoothie, for example, involves two physical changes.
• The change in shape of each fruit and the mixing together of many different pieces of fruit.
• Because none of the chemicals in the smoothie components are changed during blending (the water and vitamins from the fruit remain unchanged), we know that no molecular reconfiguration took place.
• This is a physical change because physical change did not cause the fruit to become a fundamentally different substance.
• A chemical change could have caused a substance to change into something chemically new which in this case is not true.
