Which of the following is an example of a physical mixture?

  1. Water

  2. Salt

  3. Concrete

  4. Alcohol

The correct answer is: Concrete

Concrete is an example of a physical mixture because it is made up of different physical components such as sand, gravel, and cement that can be easily separated. Water, salt, and alcohol are all pure substances that cannot be separated into different components by physical means, making them incorrect options.
