      Hi Laura,

      The video explains the physical changes. We´re going to study 2: Reversible and Irreversible.
      Reversible means that when you mix two things, you can separate them later. For example, salt and water. If you evaporates water, you have the salt.

      Irreversible means that when you mix tow things, you CAN´T separate them late. For example, cement and water creates solid cement, and you CAN´T separate.

      Do you understand better now? =)

      Hi Nazaret,

      I´m going to upload a video with an explanation soon.

      Meanwhile, REVERSIBLE means that when you mix, later you can separate.
      IRREVERSIBLE means that when you mix later you CAN´T separate.
      In the Laura´s comment, there´s a larger explanation =)

    Maria the previous message is wrong, my answer is:
    REVERSIBLE:is when a material returns to its normal state. Example:fill a plastic bottle with water and freeze it, when you defrost it becomes water again.
    IRREVERSIBLE:that it cannot return its normal state. Example:when you mix water with cement, a hard base remains that cannot return to its previous state.

    This is the homework:

    -REVERSIBLE CHANGES. Can be undone or reversed. When you freeze water, you obtain ice and when you heat the ice you obtain again water.

    IRREVERSIBLE CHANGES. Are permanent and can't be undone. When you cut a slice of ham, you can't put again the slice of ham.
