A Trombone requires larger vibrations and more air to play well, and thus requires a larger mouthpiece than the trumpet.
Larger (longer and wider) pipes have a lower resonant frequency than smaller ones. The typical "trumpet" (which is often actually a cornet) plays about two octaves higher than a typical tuba.
Tuba, it is the longest so it creates the lowest tones. In order it would be tuba, baritone and trombone. Baritone and trombone are basically the same but baritone sounds a bit better at the lowest part of its range.
There are many brass instruments smaller than a tuba, because the tuba is the largest of the brass instruments. The instruments smaller than it in order from largest to smallest are: Baritone Horn, Euphonium, Trombone, Trumpet, Cornet, Piccolo Trumpet.

Trumpet, by two octaves

A trumpet uses valves and is pitched higher than a trombone. The trombone uses a slide instead of valves, and is pitched between the trumpet and the tuba.

Assuming you mean "tuba" and assuming you mean "why does the tuba play lower notes than the trumpet," the basic answer is, because the tuba is longer (it has more tubing).
There are many brass instruments smaller than a tuba, because the tuba is the largest of the brass instruments. The instruments smaller than it in order from largest to smallest are: Baritone Horn, Euphonium, Trombone, Trumpet, Cornet, Piccolo Trumpet.
Valves. They're used to change the pitch.
I believe that the trumpet is the highest in te Brass famly, and the tuba is the lowest. In general, the bigger instrument is the lowest.
