Lil, I can see you are lacking some text in 4. and a picture but may I also give the advise that, if you post each question individually, we know from experience there is a higher chance of getting questions answered.
Along with that, we may not just answer test/quiz answers by writing a letter/number to each question. In that case it is best you try your self and some may take the time to check of they are correct.

But I'll be glad to help you with the first one, as we like to say that when we observe or measure on a physical properties we do it without changing the composition of the matter. It could be melting point, boiling point, density, polarity and so on.
