Why does an electric bulb bang when it is broken?
Light bulbs have most of the air removed, that is there is a partial vacuum inside the bulb. So, when they break atmospheric pressure pushes the on the glass where it is weakened and air rushes somewhat violently into the bulb.
Why is glass used to make electric bulbs?
Glass is used in light bulbs because it's clear (passes the light through), can withstand the heat generated by the filiment and does not leak air to the inside of the bulb. And, it's cheap and easily formed into the required shape(s)
Is there air in light bulbs?
No, there is a vacuum or inert gas such as argon or nitrogen inside light bulbs to prevent oxidation and prolong the lifespan of the filament. Air does not play a role in the functioning of a light bulb.
Why bulbs have vacuum inside?
Because if the thin filament wire was heated in regular air it would burn up.
WHAT WILL HAPPEN IF THE ELECTRIC BULB S FILLED WITH OXYGEN GAS?
If an electric bulb is filled with oxygen gas, the filament inside the bulb would burn brighter and hotter than if it were filled with normal air. However, this can be dangerous as oxygen supports combustion and can increase the risk of a fire hazard if the filament overheats. It is not recommended to fill electric bulbs with pure oxygen gas.
What should you do during the volcanic eraption?
stay inside dont breath the air
What would happen inside a light bulb if it was filled with air?
It would no longer work. Light bulbs are usually under vacuum and if air gets in the filament blows.
Why is argon used to prevent the evaporation of tungsten in electric light bulbs?
Argon is used in light bulbs because it is an inert gas that does not react with other elements. This prevents the tungsten filament from reacting with oxygen in the air, which helps to prolong the life of the filament. Additionally, argon helps to maintain a stable environment inside the bulb, allowing the filament to operate at higher temperatures without burning out.
What are the kinds of thermometer used to measure air temperature?
The instrument usually used to measure air temperature is the maximum minimum thermometer. It consists of a U shaped tube with bulbs at each end and mercury at the bottom. Air heats or cools the bulbs causing the air inside to expand or contract, therefore pushing or pulling the mercury upwards or downwards.
What gas is used inside the bulbs?
Assuming the question is referring to incandescent light bulbs (the ones with the glowing filament), Argon is the gas used.Argon is a harmless gas found in air, and is used because it cannot react with the hot filament.
What is inside the new Adidas soccer ball that sends a radio signal to the referee's watch when it crosses the goal line?
probably an electric device that has a sensor inside as well as air
Does a common electric fan pulls the air from outside the room or it simply circulates the air inside the room?
A common free standing or ceiling mounted fan simply circulates air round the room.
