Why does a cathode ray tube have low pressure inside?
Low pressure inside a cathode ray tube? How about nopressure inside the tube! In a cathode ray tube, the "cathode ray" is an electron beam that is used to paint a "picture" on the phosphor coating on the inside of the tube. (We look at the "picture" from the other side of the glass on which the coating is laid down - the outside.) An electron is a lightweight little dude. It weighs about 1/1836th as much as a single proton, so anything, any gas atoms that are in the flight path of an electron will cause it to scatter. That means we need to pump all the air out of the inside of the tube. After we remove all we can, we fire a "getter" (a chemical coated onto a small area inside the tube) which will bind any remaining gas molecules left inside the tube to complete the evacuation process. No more pesky atoms to get in the path of the electron beam and scatter it all over the place.

Cathode Ray Tubes are potentially dangerous because they are vacuum sealed and can implode. This can cause the shattered glass to fly outward and also exposes the toxic coating inside of the tube.
What happen when a test tube of liquid is heated improperly?
- the test tube may break- the liquid can be spread outside
Why do not point the test tube to anyone nor look into the test tube while it is being heated?
Because if the experiment being conducted in the test tube is explosive or very reactive then it can spit out stuff and this can be dangerous to your eyes or skin. so by pointing the test tube away then you won't harm anyone if anything spits out

How do you repair a broken tuba?
That depends on what's broken. If it's really broken, and you have no idea how to fix it, I'd STRONGLY recommend taking it to a reputable instrument repair shop. They have the tools and expertise to fix it. Anything you try to do to fix it might just make it worse.
