Answer: Many elements produce colors in the flame when heated.
Explanation:
The origin of this phenomenon lies in the arrangement, or “configuration” of the electrons in the atoms of the different elements In the flame test, if this energy has the form of visible light, the flame will produce a color characteristic of the element.
In a solid, molecules are packed together, and it keeps its shape. Liquids take the shape of the container. Gases spread out to fill the container. Solid is one of the three main states of matter, along with liquid and gas.

The number of molecules of water is calculated as follows
find the moles of water= moles=mass/molar mass
moles = 69.1g/18 g/mol = 3.84 moles
by use of Avogadro law constant
that is 1 mole = 6.02 x10^23 molecules what about 3.84 moles of water
the molecules of water = (3.84 x 6.02 x10^23) = 2.312 x10^24 molecules
