What is a working principle of mercury vapour lamp in 4 to 5 lines?
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.
What is vapour liquid equilibrium data?
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
What role does a compessor play in a refrigeration system?
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 do you calculate the efficiency of vapour absorption machine?
how to calculate the vapour absorption mechine efficiency and per TR steam consumption
Unit of water vapour diffusion resistance factor?
unitless
What is one way in which you can identify the elements that are used in various street lights?
By the colour of the light that they emit. Sodium vapour lamps produce yellow/orange light while Mercury vapour lamps produce white light.
Will mercury vapour work in a sodium vapour fixture?
no
Is Mercury vapour compressable?
Any vapour is compressible.

What actors and actresses appeared in Mercury Vapour - 2008?
The cast of Mercury Vapour - 2008 includes: Clough Rachel as The Girl
When mercury boils is a gas produced?
Yes, mercury vapour.
Why mercury lightis off after some time?
due to condensation of mercury vapour
What has the author William Harold McCurdy written?
William Harold McCurdy has written: 'The striated discharge in mercury vapour ..' -- subject(s): Electric discharges through gases, Mercury
Use of choke in tubelight?
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.
What happens if you use a mercury source instead of sodium vapour lamp in diffraction grating experiment?
sodium vapour lamps produce much higher light output (about 90 lumens/watt) they cannot be used in lighting applications where colour-rendering property is very crucial. This is because most of the light emitted from a sodium vapour lamp is concentrated in the yellow part of the visible spectrum (around 580-590 nm) On the other hand, a mercury vapour lamp is quite suitable for lighting applications. This is because, the mercury vapour lamp can feed almost the entire visible region (380-780 nm) of the human visual system.
Why does exhaled air saturated with water vapour?
water vapour is produce during respiration
Fluorescent lamp low pressure mercury vapour?
A fluorescent lamp refers to a low pressure mercury-vapor gas-discharge lamp that uses fluorescence in order to produce visible light. It is also called a fluorescent tube.
