A container of hydrogen gas and oxygen gas contains separate molecules of H2 and O2, while a container of water vapor contains H2O molecules. The hydrogen gas and oxygen gas in the first container can react to form water vapor under certain conditions.
The temperature of hydrogen gas in a sealed container can vary depending on the conditions it is stored in, but it is typically measured in degrees Celsius or Kelvin.
To make your own glow stick at home, you will need hydrogen peroxide, a fluorescent dye, and a small container. Mix the hydrogen peroxide with the dye in the container, and then seal it tightly. When you shake the container, the chemical reaction between the hydrogen peroxide and the dye will produce a glowing light.
One common way to test for hydrogen gas is to use a lit splint. When a lit splint is brought near a sample of hydrogen gas, it will produce a squeaky pop sound if hydrogen is present. This is due to the combustion of hydrogen gas in the presence of oxygen.
Yes, hydrogen gas can be collected over water by displacing the water in a container with the gas. Hydrogen is less dense than air so it will displace the water, allowing the gas to be collected in the container while the water is pushed out.

The hazard symbol you should find on a container of hydrogen is a flame symbol indicating that hydrogen is highly flammable.
A container of hydrogen gas and oxygen gas contains separate molecules of H2 and O2, while a container of water vapor contains H2O molecules. The hydrogen gas and oxygen gas in the first container can react to form water vapor under certain conditions.
In a bottle of hydrogen and oxygen the two elements are intermingled but remain chemically separate and distinct. You have H2 molecules and O2 molecules in the same general space. In a bottle of water the hydrogen and oxygen are combined into a single substance, forming molecules of H2O.

Transported? Mostly in water to be separated at a lab then contained in a separate container to pressurize into a smaller container to be shipped.
Hydrogen gas used for fuel would have to be contained in a pressurized container. You would not combine it with any other elements inside the container.

The hydrogen can be "trapped" as H2(g), hydrogen gas. You cannot trap just H.
You can lower the density of hydrogen (or any) gas by heating it in a container where it is free to expand, like a balloon.
