It may stand for 'Paid Time Off'
Explanation:
I need more context but that's probably it.
1) Compounds:
a) Chemically combined.
b) Components change properties.
c) Fixed proportions.
2) Mixtures:
a) Physically combined.
b) Components retain properties.
c) Variable proportions.
3) Both:
a) Made of elements.
b) 2 or more components.
A compound is a pure substance because its molecule cannot be broken down into simpler particles by physical means. For example water (H₂O) is a chemical compound made of two elements (hydrogen and oxygen).
In chemical change new substances are formed, the atoms are rearranged and the reaction is followed by an energy change.
There are no chemical bonds between substances in the mixture.,For example, mixture is solution of water and alcohol.

1 mole of any gas is 22.4 L.
Not really sure if that answers your question but that's what i know.
Anyway if we are talking about the size then usually gases are filled with empty space.
