In a cathode ray tube where do the particles originate and what do they move toward?

The particles originate from the Cathode in the neck of the tube. They are liberated by a heater. The electrons thus liberated are attracted by the Anode, by applying a high voltage to it.
In a CRT there are several anodes, the largest and biggest is formed by a coating inside the tube towards the screen. This attracts and accelerates the electrons in a stream of particles known as a 'cathode ray'. They carry on in a straight line, once accelerated, until they hit the screen and cause a phosphor coating to glow, on the inside surface of the screen.
The cathode ray can be bent from it's course, by using electromagnets arranged around the neck of the tube.

In electrolysis electrons move between two metal strips called?
Electrodes, the positive side is called the Cathode and the Negative side is called the Anode.The anode and cathode. The anode is positively charged and the cathode is negative.
What happens to particles in a substance when its heated or cooled?
In a solid, the particles start to vibrate a lot.In a liquid, the particles begin to move around faster and faster.In a gas, the particles move extremely fast through the air.
Which particles move parallel to wave motion?
The particles of the wave (for compressive waves). Or for transverse waves, yet the particles move parallel to the wave too.
What particles move around the nucleus in constant and random motion?
Electrons are the particles that move around the nucleus in constant and random motion.
What happens to the motion of particles in a solid and liquid and gas?
In a solid the particles are packed tightly together in a more raged formation . in a liquid the particles move passing each other in a gas the particles move freely in the space they have

What is the evidence that show cathode rays consists of charged particles?
in a cathode ray tube the cathode rays move towards the anode(positively charged) fixed plate.
How did the cathode's tube experiment lead to the conclusion that atoms contain electrons?
because Thomson saw the ray move from the cathode to the anode so the particles have negatively charge
Why do cathode rays move from the negative end of the tube to the positive end?
Because an electron carries a negative charge and in electricity, opposites attract. Particles with a negative charge will be drawn to the positive charge in the cathode tube.
When will particles move faster?
Molecules move faster when they are heated.add. And of course they may be accelerated by attraction in a Cathode Ray Tube, or a van der Graaf Accelerator.
How is the formation of anode and cathode rays?
Goldstein used a gas discharge tube which had a perforated cathode. When a high electrical potential of several thousand volts is applied between the cathode and anode, faint luminous "rays" are seen extending from the holes in the back of the cathode. These rays are beams of particles moving in a direction opposite to the "cathode rays," which are streams of electronswhich move toward the anode. Goldstein called these positive rays Kanalstrahlen, "channel rays" or "canal rays", because they were produced by the holes or channels in the cathode
Describe the motion of air particles inside a ball?
They move toward the exit to escape the ball.
What way do water particles move a. toward shore b. in a circle c. backward d. sideways?
b.
How electrons was discovered?
In 1897 J.J.Thomson conducted an experiment in which he took a discharge tube with very less gas molecules in it.When he connected a cathode and an anode, some particles which he called cathode rays passed from the cathode to anode. OBSERVATION: @when a negative and positive plate were kept, the negative plate repelled the rays while the positive one attracted them. This means the ray's particles are negatively charged. @if a paddle wheel was kept in the path of the ray, the wheel started rotating, which means, these particles have energy. @if an object and screen were kept, the shadow of the object fell on the screen after a green glow.This means these particles always move in a straight line. It was then discovered by J.J.Thomson that these particles were electrons!
What is meant when a system has reach equilibrium?
when the substance can cross the cell membrane, its particles will tend to move toward the area where it is less concetrated
In the electrolytic cell electron flows from?
Electron flow is from anode (+) to cathode (-)
