Cathode-Rays are streams of electrons. Having a charge of -1 and a small mass (about 1 /1836th of a proton), they interact easily. Since you don't want them to interact with the atoms in the tube (air, etc.), you evacuate the tube, leaving it in as near a vacuum state, or zero PSIA, as possible.

Electrons were discovered as a result of investigations of the flow of electricity through an evacuated glass tube?

When trying to lead class evacuated tube so I collected in the same order of draws plastic tubes true or false?
I say true
In the Thomson experiment to determine the Specific charge of an electron If the pressure in the discharge tube is made is made as low as nearly zero dose conduction takes place?
In Thomson's experiment the tube used is evacuated i.e. there is vacuum inside.
What kind of spectrum does a neon sign produce?
The color from a neon sign is created by the gas being used inside of the tube. the bandwidth is very narrow so only a single color is output from the tube.
How does an emission spectrum of a gas in a discharge tube differ from a white light spectrum?
It differs by that white light spectrum is continuous and consists of light of all wavelengths. Emission spectrum is not continuous. It consists of bright lines at specific wavelengths, with complete darkness between them.
What evacuated tube would you use to draw for electrolytes?
red topped tube
What does a evacuated tube system requires?
What does the evacuation system
Who discovered electrons through an evacuated glass tube?
JJ Thompson
What gas is used in a vacuum tube?
A vacuum tube does not contain any gases. All the gases are evacuated from the tube and only vacuum is left.
What decreases the vacuum draw of evacuated tube?
Both time and temperature can decrease the vacuum draw of an evacuated tube. Hence the provided expiration dates and storage temperature of tubes. The vacuum of a tube will decrease if it is too old or if stored at a colder temperature than recommended.
Is it require to mix and evacuated tube type light blue in time of collection?
No
What color tube is for blood cultures?
The yellow evacuated tubes are for blood cultures.
What is the common needle gauges used for drawing blood with a evacuated tube?
21g
When collecting blood in a black top evacuated tube how full should it be?
It needs to be 100% full as the light blue tube.
What color test tube is for blood cultures?
The yellow evacuated tubes are for blood cultures.

Which color topped evacuated tube is used for collection of blood for electrolyte testing?
SST or Tiger Striped
