Cutting a glass tube is a physical change because the cut glass tube still has the same chemical composition as the uncut tube. Nothing has changed except the physical appearance of the glass tube.

It is reversible because bending of glass tube is glass tube not the make anything .

Water will move higher in a narrow glass tube than in a wide glass tube because of?
It is because of Capillary action, the adhesive forces for water are effective in narrow tube, in a wide tube the weight of water resists the upwards movement of water.
Why when placed in a glass tube water touching the glass is pulled slightly upward?
Meniscus. Essentially it is because water adheres to the glass.
What did William Crookes discover with his glass tube experiment?
Cathodes(electrons) (-)
When light enters glass from air it changes direction. What is the change of direction called?
If the light is entering from air or a vacuum, the light will slow down. The affect of this, if the light hits the glass at an angle, is that the direction of the light will change.
What supports the column of mercury inside the glass tube of a barometer?
Another tube. Or in a solid manomometerof any type, a hollowed out, encapsulated space.
Is softening a glass tube by heating is a chemical change?

it is a physical object...
How do you beat level 60 of liquid measure?
TUBES going left to right: Attach a down and right bending tube on #1 (first column) Do not attach anything to #3 (second column) Attach a right bending, then down bending, then right bending tube on #3 (third column) Attach a right bending tube on #1 (fourth column) Attach a right bending tube on #2 (fifth column) Attach a left bending, then straight tube on #2 (sixth column) Do not attach anything to #3 (seventh column). GLASSES Place a vertical 3 glass directly under the #3 tube in the second column. Place the horizontal 3 glass directly on top of horizontal 4 glass stretching from 2nd-4th column. (leaving only one space open on the 4 glass in the fifth column) Place the vertical 2 glass directly next to the 4 glass in the sixth column. Place the vertical 3 glass directly next to the 2 glass in the seventh column.
Where can a person find tube bending services?
There are multiple tube bending services to be found online on various websites. The most recommended websites are 'Tube-Bending-Service' and 'Barnshaws'.
What has the author John Gillanders written?
John Gillanders has written: 'Pipe & tube bending manual' -- subject(s): Pipe bending, Tube bending
Is heating of ammonium chloride in a test tube a physical or chemical change?
This is a chemical change (thermal decomposition).
Where are there neon tube bending schools?
the Dorian professional school in France provides a solid formation in neon bending
Why bourdon tube is oval in shape?
Because it will provides maximum dflection in Only vertical direction and no any other bending of tube due to pressure occurs.instead if cross section is circular then along with vertical defletion or bending of tube there is also bending along horizaotal direction,which leads to error.so it has oval shape............got it
If you have steam in a test tube which condenses to moisture-is this a physical or chemical property?
You have a phase change which would indicate a physical change since the substance remains the same in composition.
What is Hard test tube?
a hard glass test tube is a test tube made out of glass that is almost impossible to break.
Is a glass tube a conductor or a insulator?
It is a insulator. The glass does not have free electrons to flow as current, and the air in the tube is also an insulator.
