Why does the water rise in the measuring tube when you use hydrogen gas?
When hydrogen gas is produced in a chemical reaction, it displaces the water in the measuring tube since hydrogen is less dense than water. As a result, the water level in the tube rises as the lighter hydrogen gas occupies the space previously filled by water.
When water in a glass tube is heated the level of water in the tube?
rises because the water expands when heated, causing an increase in volume which leads to a higher level in the tube.
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.
What is the dip in the water in a test tube called?
The dip in water in a test tube is known as the meniscus. It is caused by the surface tension of the water, which causes it to curve slightly at the edges of the container. When measuring liquids in a test tube, readings are typically taken at the bottom of the meniscus.
Will pure hydrogen give the same result when burning splinter inserted on the mouth of the test tube?
When burning hydrogen at the mouth of a test tube, it will produce a squeaky pop sound due to the rapid combustion of hydrogen gas. This reaction occurs because hydrogen easily reacts with oxygen in the air to form water vapor, releasing energy in the process. The splinter would likely catch fire and burn more vigorously due to the presence of hydrogen gas in the test tube.

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...
What is the optimal method for measuring the water level in a container using a hose?
The optimal method for measuring water level in a container using a hose is to attach a clear tube to the hose and submerge the open end of the tube into the water. The water level in the container will rise in the tube, allowing you to easily read and measure the height of the water.
What will happen when a inverted test tube is inserted into a measuring cylinder containing water?
As the inverted test tube is inserted into the measuring cylinder containing water, the water will rise up into the test tube due to atmospheric pressure. The level of water inside the test tube will stabilize at a certain height once the pressure inside and outside are balanced. This can be used to measure the volume of the test tube.
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.
How do you find the volume of water in a beaker?
7.6 ml
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.
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?
