Compare the entropy of a firecracker before it is lighted to its entropy after it explodes

1 answer:

3 0

The entropy of a firecracker is much less before it explodes than afterwards.
Entropy is a measure of the degree of disorder in a system.
Before the explosion, everything is packed in a small volume inside a cardboard tube.
After the explosion, the contents have been converted largely to gases and finely divided solids spread over a large volume of the sky.
The latter situation is more disordered, so it has a higher entropy.

These substances are all ____. H2O2 Li NaCl O2

Bogdan [553]

Answer: pure substances.

Explanation:

The given substances are:

H₂O₂
Li
NaCl
O₂

All what surrounds us, which has mass and occupies spaces, is matter. There are two kind of matter: pure substances and mixtures.

Pure substances have a uniform and constant composition. On the other hand, mixtures are combinations of two or more pure substances in any arbitratry ratio.

Pure substances may be elements or compounds. The elements are the substances conmposed by one only kind of atom. In the list of substances given, Li and O₂ are elements: all the atoms in Li are lithium, and all the atoms in O₂ are oxygen atoms.

Compounds are the chemical combination of two or more different kind of atoms. In the given list H₂O₂ and NaCl are compounds. As you see, H₂O₂ contains atoms of hydrogen and oxygen, chemically bonded, in a fixed ratio (2 atoms of hydrogen by 2 atoms of oxygen). And NaCl has atoms of Na (sodium) and Cl (chlorine), chemicaly bonded, in a fixed ratio (1:1).

There are only 118 known elements and you can find them in any modern periodic table. Therer are virtually infinitely many compounds since many different combinations of the elements can be attained.

Elements and compounds have in common that they are classified as pure substances.
