When you use hydrogen gas the water rises in the measuring tube why?

Hydrogen gas (H2) is not very soluble in water, and so it will displace the water in the container, thus making the level rise.

When water in a glass tube is heated the level of water in the tube?
Falls and then rises
Does liquid water rise higher in a narrow tube or a wide tube?
Rise or fall of liquid in a small passage or tube. When a glass tube of small internal diameter is inserted into water, the surface water molecules are attracted to the glass and the water level in the tube rises. The narrower the tube, the higher the water rises. The water is said to "wet" the tube. Water will also be drawn into the fibres of a towel, even if the towel is in a horizontal position. Conversely, if a glass tube is inserted into mercury, the level of the liquid in the tube falls. The mercury does not wet the tube. Capillarity is caused by the difference in attraction of the liquid molecules to each other and the attraction of the liquid molecules to those of the tube.
How does coal burning create energy?
the heat from the burning coal heats water which rises through a tube making a current and turning turbines
Function of bent tube earth thermometer?
The bent tube Earth thermometer is a kind of a measurement that is used for measuring temperature of the earths crust.
What is the function of a J-tube and a U-tube?
a U-tube is a glass tube shaped in the form of letter "U" which can be used as a manometer, and is used in measuring the pressure of liquids.

How is hydrogen captured after it is separated from water?
It is captured in an upside down test tube or a gas collecting tube.

Why is there a chance of explosion when hydrogen chloride gas is led into water by a delivery tube?
Hydrogen chloride in water (hydrochloric acid solution) is not explosive.
What happens to the level of water in a test-tube as hydrogen is produced?
Ya... In a test tube add some aluminum foils and some amount of NaOH... Introduce the flame near mouth of the test tube... Then see the magic...
How do you find the volume of water in a beaker?
7.6 ml
What will happen when a inverted test tube is inserted into a measuring cylinder containing water?
the air would be trapped in the measuring cylinder. basically, nothing would happen
The test for hydrogen consists of?
Put a light splint into a test tube containing hydrogen. If it pops its hydrogen if not something else. But make sure there oxygen in the test tube too or else the hydrogen wont react with Oxygen to produce water (this reaction causes the pop sound)
What is a gas tube used for in a science?
what is a gas measuring tube
How do you find out if a gas if a hydrogen?
Light a wooden splint and hold it in some of the unknown gas(which is supposedly hydrogen). If there is a loud "pop" sound, then it is hydrogen. there is a very quick and simple way to do this you have to trap the gas in side a test tube but make sure it is half full of water, trap the gas and if when you turn the test tube upside down and the water stays in the same place the bottom of the tube (which would now be top) then you have "H" HYDROGEN
Why is double the amount of gas collected in one of the test tube on electrolysis of water name the gas?
Water contains two parts hydrogen and one part oxygen (2 H and 1 O = H2O) Because of this, the amount of hydrogen and oxygen produced during electrolysis of water is in a 2:1 ratio. In electrolysis process, hydrogen goes to one test tube and oxygen goes to another. Because Water contains 2 part hydrogen, the amount of gas collected in one tube is double the amount collected in the other.
If an inverted tube containing air is placed above a test tube of hydrogen why would the tube of air give a positive test for hydrogen after a few minutes?
This would happen because of the process of diffusion. Hydrogen molecules would move from the hydrogen test tube where they are highly concentrated to the air test tube where their concentration is low.
