Which of the following statements correctly explains why physical properties of a substance can be used to separate mixtures? (1 point) When substances are mixed together, they retain their physical properties. Mixtures contain different substances with different properties and chemists can separate one item from the mixture by forcing it to undergo a chemical change. When substances are mixed together, the mixture assumes the physical properties of each individual substance. When substances are mixed together, you can see each individual component.
