How would you use capillary in a sentence?
The liquid was pulled into the small tube by capillary action.
Heating the liquid in a test tube?
it vapourise from the test tube
What is the capillary tube?
In chemistry... it's a thin open-ended glass tube for collecting small amounts of liquid. Inserting one end of the tube into liquid allows the liquid to flow upqwards. When the liquid reaches a suitable height, a finger placed over the open end (towards the top) holds the liquid in the tube - for transferring from one place to another.
Why the burette is clamped vertically?
A burette can be a hollow glass (or plastic) tube open at the top, with a small tap at the bottom. There may also be a scale etched down the tube. The burette allows a certain amount of liquid past the tap. So, obviously, unless clamped vertically, the liquid would simply pour out of the glass 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.
Why is direct heating of liquid substances in a test tube over the flame prohibited?
Provided that you use the wider kind of tube known as a boiling tube, this is not so. Of course it is dangerous to heat liquids in a narrow tube, as this can cause rapid boiling and the shooting of the liquid out of the tube.
What would the pressure be in a liquid contained in a vertical tube sealed at the top with a submerged open bottom be?
It would be the same as the pressure in the liquid outside the tube at the open end- the deeper it is in the liquid, the higher the pressure.
Why is there oil in your spark plug tube?
Most likely cause is the cam cover gasket is leaking.

Is there inert gas inside a thermometer?
No. The tube inside a thermometer is vacuum. If there was a gas inside, the pressure changes due to temperature changes would cause the liquid inside to expand/contract unevenly.
What is the effect of change the length of tube input liquid?
The effect of changing the length of tube input liquid depends on the type of device being used and the types of liquids being used. In general, increasing the length of the tube can cause a decrease in the amount of fluid being inputted. This is because the longer the tube, the more resistance the fluid faces when being forced through it. This resistance can cause a decrease in the velocity of the fluid, resulting in a lower flow rate. For example, when using a syringe to inject a fluid, increasing the length of the tube can cause the fluid to move slower, resulting in a smaller amount of fluid being inputted. If a pump is used to move a fluid, then increasing the length of the tube may increase the pressure the pump has to work against. This can cause the pump to work harder, resulting in less efficient operation, and possibly overheating. Finally, the type of liquid being used can also play a role in the effect of changing the length of the tube. For example, if a liquid is highly viscous, then increasing the length of the tube can cause an even larger decrease in the amount of fluid being inputted. This is due to the increased resistance the liquid has to overcome when being forced through the longer tube.
Heating the liquid in a test tube?
it vapourise from the test tube
How would you separate the salt from the water and still have the water left?
Simple collect the water gas and cool it using a condenser in a condensing tube which will cause the water to return to liquid state and collect it in a beaker
What can cause transmission fluid to come for the filler tube?
The most likely cause of transmission fluid coming up the filler tube is air in the fluid. This can be caused by a leak in the system and should be checked by a mechanic as soon as possible.
How liquid pressure vary with density of liquid?
Imagine a glass tube with equal cross-section of 1 square cm and of length 100 cm. Fill the tube with the liquid of density 'd' to the 75cm mark.The pressure at the bottom of each tube is the force exerted per unit area by the column of liquid in the tube. We have conveniently selected tubes with 1 sq cm (unit area in CGS system) cross sectional areas. So the weight of the column in the tube would be the pressure. Hence the pressure in the tube would be1) Weight of the 75cm liquid column = 75 x d x g = 75dg dynesThe presuure depends on the density in a linear proportion.Read more: How_does_liquid_pressure_vary_with_density_of_liquid

Why does a liquid rise in a capillary tube?
This is due to Surface Tension. The molecules/atoms of the liquid are atrracted by the particles of the solid and thus the liquid rises in the capilliary tube.
