Answer:

A.  gases only

Explanation:

It is only in gases that the particles are very far apart so they can fill their contains.

There are four major states of matter which solid, liquid, gases and plasma.

  • Particles of a gas have very weak attractive forces between them.
  • They do not have fixed volume nor shape
  • They easily fill up any containers they are put into.
  • Gases are compressible and moves randomly in a straight line.
  • Liquids and solids do not fill up containers.
  • Liquids although have weak forces but they are better attracted than gases.
  • Solids have fixed and definite volume.

So, option A is the perfect answer.

The 5 postulates of Daltons' atomic theory are:

1. All the matters are made of atoms.

2. Atoms of different elements combine to form compounds

3. Compounds contain atoms in small whole-number ratios

4. Atoms can neither be created nor destroyed . (This was later proven wrong )

5. All atoms of an element are identical and have the same properties (This was later proven wrong as atoms of same element may be different in case of elements having isotopes )

Therefore, options c and d are the answer.

If the temperature we're to go down how would that effect the solubility of each solute
vova2212 [387]

well when there is more kinetic energy in a solution the higher its temperature is going to be so the more the molecules are able to be help together, the lower the temperature the more difficult it would be to break the molecule apart in order to bond with it.
