Answer:
A modern statement is: Avogadro's law states that, "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules." For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.
When a physical change occurs, the arrangement of particles within the substance may change, but the atoms in the molecules remain bonded together.

We know about all the colors in the rain bow but do you know how most of them are made?
Red and blue and yellow can make sooooo many different colors if you mix them together.
For example red + blue = purple! This is because red, blue and yellow are primary colors and these colors are colors that can make up other colors.
