It depends on the tube's construction. Assuming a graduation every one millimetre, a 50 mm high tube can measure to +/- 0.5 ml accuracy. A 200 mm high (very thin!) tube, also with one mm graduations, is four times as accurate.
You need to state the smallest actual graduation to get your answer, and be aware that the liquid's meniscus affects reading confidence.

The uncertainty of a 50 ml glass gas measuring tube would depend on the precision of the markings on the tube. If the tube is graduated in milliliters with marks at every 1 ml, the uncertainty would be ±0.5 ml. If the marks are at every 0.5 ml, the uncertainty would be ±0.25 ml.

What is the use of gas measuring tube?
A gas measuring tube is a laboratory glassware used for collecting and measuring the volume of gases produced during a chemical reaction. It helps in determining the amount of gas produced and studying the stoichiometry of the reaction.
If a chemical reaction produces a gas how can that gas be captured in a test tube?
To capture a gas produced in a chemical reaction in a test tube, you can use a rubber stopper with a glass tube inserted into it. As the gas is produced, it displaces the liquid in the test tube and fills the space above. The glass tube allows for a controlled release of the gas when needed.
What is a gas- collecting tube?
A gas-collecting tube is a device used to trap and contain gases for analysis. It typically consists of a sealed tube with one end submerged in the liquid in which the gas is produced, allowing the gas to travel up the tube and collect at the top for measurement or further study.
What gas is evolved when a few crystals of potassium nitrate are heated in a hard glass test tube?
Nitrogen dioxide and oxygen are released.
When magnesium reacts quickly with hydrochloric acis to produce hydrogen gas in a glass tube with a rubber stopper why would the rubber stopper burst of?
The reaction between magnesium and hydrochloric acid produces hydrogen gas, which builds up pressure inside the closed glass tube. If the pressure exceeds the strength of the rubber stopper, it will burst off to release the built-up pressure and prevent the glass tube from breaking due to the increased pressure.

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.
What is a gas collecting tube used for?
A gas collecting tube is used to collect and store gases during chemical reactions or experiments. It allows gases to be collected and measured conveniently without escaping into the environment. The tube can be connected to a gas measuring device for accurate measurement of gas volume.
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.
What are neon signs made out of?
They are made out of glass as a the tube and there is no active filament what actually creates the glowing is there is a gas inside the tube and the electricity that runs to it creates the gas to ionize which creates light.
What is a collecting tube?
A gas-collecting tube is made of glass and has a cylinder shape with a valve at one end of the cylinder. Most gas-collecting containers have a gauged volume on them. They are used in science for the purpose of taking samples of a gas.
Why collect hydrogen gas in a test tube rather than glass jar?
Hydrogen gas is less dense than air and tends to rise quickly, so collecting it in a test tube allows for easier capture and observation of the gas. Additionally, a test tube typically has a smaller opening, which reduces the risk of the gas escaping. Finally, a test tube is easier to handle and transport compared to a larger glass jar.

How does gas thermometer functioning?
Gas thermometers operate by measuring changes in gas volume as temperature varies. When the temperature rises, the gas inside the thermometer expands, increasing the pressure and moving the liquid in a glass tube. This movement is then converted into a temperature reading based on the calibrated scale of the thermometer.
How floroscent tubelight works?
The glass tube is filled with mercury gas. Electricity causes the gas molecules to vibrate faster. The increased motion excites phosphorous in the tube and causes it to give off visible light.
