  1. False

    Explanation:

    Chemical changes do change the composition of the substance. However, physical changes do not; physical changes simply alter the physical form of the substance.

    For example, a melting ice cube is undergoing a physical change, but its overall composition of H2O isn't changing. It's just changing from a solid form to a liquid form.

    Hope this helps!

  2. A physical change are changes which alters a substance without changing its composition. So physical means without changing its substances. For example if we changed a persons appearances it would be a physical change, but that doesn't change who they are as a person or their identity. So, true.

  3. Fals. Definitely not true. Mentally, your mind changes, and you become smarter with the choices you make. Emotionally, you can become more attached, or distant, depending on the person. ­čÖé

  4. True, in a physical change, some of the physical properties of the substance may be altered but the chemical composition remains the same.

    Option True

    Explanation:

    The matter can undergo variations in physical or chemical. The physical changes of a matter occur when the matter undergoes changes in the physical properties like change in the state of matter, weight, etc.

    But the matter's chemical compositions will remain constant in case of matter undergoing physical change. While in chemical change, the matter will undergo change in the composition but there will be no change in the physical properties. Hence, the given statement is true about a physical change.

  5. True

    Explanation:

    Yes this statement is true.

    In a physical change, some of the physical properties of the substance may be altered and the chemical composition remains the same.

  6. Hey there! Hello!

    I would say this statement is false false false. As someone who went through adolescence not that long ago, I can say with certainty that both physical and mental changes are yielded from the process. During this time, kids tend to start growing hair places, grow taller, start getting deeper voices, and go through physical changes related to reproduction. 

    There's also a lot of other stuff that goes on in their heads, too. Hormones start kicking into high gear, meaning a lot more emotion will be felt than ever before. Kids will start to really consider their identity and who they are, as well as things like their sexuality and who they are attracted to, especially in today's day and age where kids have a lot more exposure to that kind of stuff. Kids may also really start to think about why their reproductive organs are changing so much, which can bring on a lot more emotion and urge on top of emotion and urge. 

    Hope this helped you out! Feel free to ask me any additional questions if you have any. ­čÖé

  7. Explanation:

    If only the form of a substance changes, you have observed a physical change. A common physical change occurs when matter changes from one phase to another. When an ice cube melts for example, it becomes liquid water. The solid ice and liquid water have the same composition.

  8. false

    Explanation:

    A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding.

  9. In a chemical change, a substance cannot change back to the form it used to be in.
    Ex. A Rusty Nail
    In a physical change, it is reversible to change back into how the substance was; shape or size.
    Ex: Freezing liquid is a physical change
    I hope you can find the answer to this question with my details!
    Hope this helps:)
