Test tube
Why is bending a glass tube a physical change?
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.
What is Hard test tube?
a hard glass test tube is a test tube made out of glass that is almost impossible to break.
Hard glass test tubes - material?
A test tube is usually made from plastic or glass and is shaped like a long tube. If used for a physics or chemistry experiment, one would use the glass test tube. If used for cultures, one would use the plastic tube and discard after use.
Give a brief history of fiber optic technology?
One day a person noticed that light shone through glass stayed inside the glass. If that glass was in a tube shape then the light was mostly confines to inside the glass regardless of how long the glass tube was. The clearer the glass meant the longer the tube could be before the light became too weak to be useful. Optic Fibre in use these days can literally cross oceans
Why it is necessary to hold the neck of the tube in the flame of the Bunsen burner?
Holding the neck of the tube in the flame of the Bunsen burner helps to sterilize the opening and prevent contamination of the contents of the tube. It also helps to create a slight updraft, preventing substances from escaping the tube. Additionally, it can help to soften the glass, making it easier to manipulate or seal the tube if needed.
Describe the structure of a thermometer?
The thermometer consists of a very fine glass tube having a very small bore and is called capillary tube. At one end of capillary tube a very thin glass bulb is provided. The bulb is filled with mercury( most of the times) or alcohol The other end of capillary tube is sealed. The capillary tube is protected by a thick glass tube called stem. On the stem are made markings. These markings are called graduations or degrees.
Is a glass tube a insulator or conductor?
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.

What is a tv tube usually made out of?
cathode ray tube
What is glass brass tube?
its a Kaleidoscope
How do you shorten length of a glass tube?
You can shorten the length of a glass tube by using a glass cutter to score a line around the tube where you want it to be cut. Then, apply pressure on both sides of the score line to snap the tube at the desired length. Be sure to wear appropriate safety gear, such as gloves and goggles, while cutting glass.
