When a current flows through Mercury vapor, it produces light through a process known as gas discharge. The electric current excites mercury atoms, causing them to emit ultraviolet light as they return to their ground state. This ultraviolet light then interacts with the phosphor coating on the inside of the lamp, producing visible light. This phenomenon is commonly utilized in fluorescent lamps and mercury vapor lamps.
Mercury vapour contained in an evacuated glass bulb.Vapour warmed.High voltage applied to electrodes inside lamp.Vapour conducts and allows current flow, excitation causes vapour to glow brightly.Little or no resistance, so requires a ballast in line.
when number of molecules into vapour state from liquid state is equal to number of molecules going from vapour to liquid equilibrium is said to have been established
In vapour compressor refrigeration system the low pressure and temperature vapour refrigerant from evaporator is compressed. where it is compressed to a high pressure and temperature. From compressor refrigerant goes to condenser where where it changes the phase. from condenser refrigerant goes to evaporator through expansion device.
how to calculate the vapour absorption mechine efficiency and per TR steam consumption
unitless
When electricity passes through the tube, it excites the mercury vapour inside, causing it to emit ultraviolet (UV) light. The UV light then interacts with phosphor coating on the inside of the tube, causing it to fluoresce and produce visible light.
By the colour of the light that they emit. Sodium vapour lamps produce yellow/orange light while Mercury vapour lamps produce white light.

Any vapour is compressible.

Yes, mercury vapour.
Low-pressure mercury-vapour lamps are coated with phosphors to convert the ultraviolet light emitted by the mercury into visible light that is more useful for general lighting purposes. This process allows the lamp to produce a broader spectrum of light, making it more appealing and efficient for human vision.

Fluorescent lamps contain low-pressure mercury vapor that produces ultraviolet light when an electric current passes through it. The ultraviolet light then interacts with a phosphor coating on the inside of the lamp, causing it to emit visible light. This process is more energy-efficient than traditional incandescent lighting.
Choke has got two functions. Initially it raises the ac voltage to some 350 V so as to initiate the discharge of electricity through mercury vapour. Once the discharge becomes activated then low voltage about 110 V is enough to maintain the discharge through mercury vapour. This is supplied by the same choke.
