What else can I help you with?
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 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.
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.
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.
Which would most likely cause the liquid in Tube A to rise?
If the liquid in Tube A is connected to a vacuum pump and the pressure in the system is decreased, the liquid in Tube A will rise due to the reduced pressure in the tube allowing the liquid to travel upwards.
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 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.
What is the relationship between the inner diameter of the tube and the height to which the water will rise?
The relationship between the inner diameter of a tube and the height to which water will rise is described by the principles of capillarity. In a narrower tube, water will rise to a greater height due to the increased adhesive forces between the water molecules and the tube's walls, as well as the reduced weight of the water column. Conversely, in a tube with a larger diameter, the height of water rise will be lower because the gravitational force has a greater influence relative to the adhesive forces. Thus, the inner diameter inversely affects the height of the water column in the 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...
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 when you blow over the mouth of a test tube which is half filled with water?
Blowing over the mouth of the test tube will create a decrease in air pressure inside the tube. This decrease in pressure will cause the water in the test tube to rise up due to the higher pressure outside the tube. Ultimately, the water level in the test tube will rise as a result of the change in pressure.
How high can water rise in a capillary tube 30 micrometers in diameter?
4.6
Does liquid water rinse higher in a narrow tube or a wide tube?
You mean rise not rinse. Higher in a narrow tube due to capillary action.
How high would a column of water rise when the outlet tube is 2 ins while the inlet tube is 4 ins?
2
How do you find the volume of water in a beaker?
7.6 ml
