Determine the density.
Explanation:
The best procedure a student can use to examine the intensive property of a rectangular block of wood is to determine its density.
An intensive property is a property of matter that is independent of the amount of matter present in it. Examples are density, melting point, boiling point etc.
Every substance in pure form have their distinct density. It is without regards to the mass and volume of such substance present.
Mass, length and volume are extensive properties that depends on amount of matter present.

M = 20 g
Volume = 12 cm³
D = m / V
D = 20 / 12
D = 1.67 g/cm³
hope this helps!
0.06 has one significant figure (unless there are zeros written after it). So I would round the result to 6000. Some teachers prefer at least 2 significant figures though.
Answer:
Explanation:
Hello,
In this case, the relationship between the mass, heat, temperature and heat capacity id given by:
In such a way, the temperature change results:
Clearly it is a positive change which means the temperature increases as heat is added.

Ok first <span>to balance O we do it like this:
2KClO3 ---> KCl + 3O2
Then </span><span>to balance K and Cl </span>
<span>2KClO3 ---> 2KCl + 3O2
So the ratio will be </span><span>2:3
Hope this helps a lot to you</span>
