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.
what are the similarities between high and low pressure
Tropical low pressure belt
I am not sure if they are proportional, but they are inversely related. High pressure makes a low vacuum, and low pressure makes a high vacuum.
A refrigerator is basically an air conditioning system. There is a high (discharge) and a low (vacuum) side to such systems. As it goes through the system, the refrigerant will change state (e.g., high pressure vapor to high pressure liquid, high pressure liquid to low pressure liquid, low pressure liquid to low pressure vapor, low pressure vapor back to high pressure vapor). This facilitates the absorption of heat from the refrigerator compartment and the exchange of that heat to the ambient air. What you're seeing there are the pressure readings (in psig) of the high pressure and low pressure sides of that system. Your refrigerator and an automotive AC system use different refrigerants, and thus have different system operating temperatures. While those numbers would be excessively high on an automotive system, I don't know if that's the case with a refrigerator. You'd need to inquire with a qualified service professional on the matter of what your refrigerator's operating pressures should be.
Yeah she have high sugar level and low blood pressure she is suffering from diabetes...
crooks tube is the tube used by William crooks in his cathode ray experiment.it has a low pressure inside and it contains an anode and a cathode in each ends.the anode and the cathode are combined by a high voltage.
Cathode ray.
cathode ray
So that the electrons are not scattered by collisions with air molecules.
C.R.T. are built to to have near vacuum so electrons can easily flow. as pressure increases this capability is reduced accordingly
In his investigations of the conduction of electricity in low pressure gases, William Crookes discovered that as the pressure was lowered, the negative electrode (cathode) appeared to emit rays (the so-called cathode rays, now known to be a stream of free electrons, and used in cathode ray display devices).
JJ Thompson passed an electric current through a gas at low pressure from the negative terminal to the positive terminal then decided that the ration is always the same regardless the gas used.
A: A CRT is a glass enclosure sitting in a vacuum. lowering the outside pressure will certainly help its stress . The other way around it may implode
fire tube & water tube . high pressure and low pressure. low capacity and high capacity.
Were composed of no charge particles .
There are two aluminum tubes coming out of the compressor. The high pressure tube goes to the condensor in front of the radiator. The low pressure tube is the other tube, and the port has a black plastic cap over it, on the low pressure tube.
