The behavior of gases in chemical reactions. That’s why the idea of atoms was proposed seriously by Dalton (as opposed to armchair what ifs from Democritus as random philosophy.)
Atoms have different masses so that makes it very hard to see patterns most of the time. But gases have behavior that depends on the number of particles, and if you look at that, you start to notice that under the same conditions, it always takes for example 2 liters of hydrogen gas to react with 1 L of oxygen gas to make water. No more, no less. You can’t make extra hydrogeny water, the way you can make different alloys versions of bronze by changing the mix of tin and copper.
Why would that be?
The simplest explanation is that it takes two hydrogen “things” and one oxygen “thing” to make one water “thing.”
There’s lots of other ways, but that was the original inspiration.

Here is your answer :-
The large mass of water in the container can divide into smaller units (drops). So water consists of small particles. All these demonstrations involving breaking a solid, dissolving a solid and pouring a liquid, together show that matter consists of small particles. This is the basis of particulate theory which states that matter consists of invisible particles.
Tapping Smoke
Drag a lit match stick into the tin can to ignite the paper. This should generate the smoke
After some time drag the tin cover onto the tin can
Record the observation in the text box.
The smoke comes out
Conclsion
Matter, whether solid, liquid or gas is made up of tiny, invisible particles
