The two properties which are used to define matter are that it has mass
and it takes up space. The other properties do not necessarily apply to
each matter. Such some matter can be a conductor of heat (such as metal)
and some not (such as non metals). Likewise, some matter can be buoyant
and float on liquid of density more than it but others would not on the
liquids of density less than it. In-fact not all the matters are
conductors of energy (such as heat, sound, electricity) or at-least a
very poor conductor of energy and tend to find application as
insulating agents (non conductors). So the only thing which is
necessarily true is that the matter would definitely have mass in even
their minutest form as atom and would take up some space.
D=m/v. (Density equals mass over volume).
So in your case density = 4.2/6
Which equals 0.7
Your units will be grams over milliliters
So your answer is 0.7 g/ml
Answer:
Law of conservation of energy states that energy can neither be created nor can be destroyed but can be changed from one form to another

Answer:
On the periodic table, each column is called a group. So, the answer is D. groups.
Explanation:
A) is incorrect because the rows on the periodic table are called periods.
B) is incorrect because the elements are what is organized on the periodic table.
C) is incorrect because the periods are the rows on the periodic table.
D) is the correct answer because the columns on the periodic table are called groups.
