Sci10 - Matter And Change

Read the first 3 definitions for matter1,2,3.  These are the scientific definitions for matter.  Which of the following is an example of matter?

An extensive property of matter is a property that depends on how much matter you have.  For example, how much volume5 of water you have depends on how much water you have. In the picture below, you have 6.6 mL of water because that's how much you've got.Of the following, which are examples of extensive properties?  Which are not?  Explain.color, mass8, weight, texture

An intensive property of matter is a property that does not depend on how much matter you have.  For example, boiling point is an intensive property.  It does not matter if you have 1 liter of water of 100 liters of water; both needs to reach 100 degrees C until they boil.Of the following, which are examples of intensive properties?  Which are not?  Explain.hardness, melting point, size

A substance has a definite composition.  In other words, a substance is just a bunch of the same stuff.  For example, if you have a glass of water, water from the middle of the glass is the same as water in the middle of the glass is the same as water at the bottom of the glass. Which of the following are examples of substances?  HINT: select ALL of the correct answers.

If we burn the paper (NO!  DO NOT BURN THE PAPER! - I'm just saying, hypothetically speaking), will we be left with paper?  The answer should be no.  In no way is what we have left after burning paper still paper.  Burning something or doing something that changes the material is called a chemical change.  Which of the following are examples of a chemical change?  When looking through the choices, ask yourself, is what I end up with the same as what I started with?  Also, the following are signs of a chemical change:1. transfer of energy2. change in color3. production of a gas4. formation of a precipitate, as solid that forms and settles out of a liquid

Find the definition for the law of conservation of mass.  According to this law, if you burn 1kg of wood, what should the mass be of the stuff that forms?  Why is it that if we take the mass of the ashes that remain after burning, it will NOT be 1 kg?
