Does the glass tube in a fire sprinkler expand more or less than the liquid inside the tube How do you know?

The liquid expands more than the glass envelope. You know this because the mechanism is designed to open the water valve to the sprinkler head when the glass envelope shatters when the liquid ruptures it as it heats up.

Does the glass tube in a fire sprinkler expand more or less than the liquid inside the tube?
The contents of the glass envelope expand and break the envelope. That allows the valve to open and release the water. The contents expand more than the tube.
Why does water in a glass tube contracts first then expand when heated?
glass is a bad counductor of heat, so at first the glass flasks expands and its volume inside increases. the liquid which has not started to expand yet, drops to fill the extra volume inside
What will happen to the liquid in the glass if a flame is lit the liquid will'?
Expand Slightly
What is the liquid in a frangible - bulb fire sprinkler?
The glass bulb inside a fire sprinkler head is filled with a heat sensitive liquid (e.g., glycerine) that expands faster than the glass bulb as it gets hotter. Eventually, it expands so much that it causes the glass bulb to burst, releasing the water behind it.The different colors of liquid contained within the bulb correlate to the temperature at which the sprinkler head will activate:Orange - 135oFRed - 155oFYellow - 174oFGreen - 200oFBlue - 286oFPurple - 360oFBlack - 440OFDifferent colors are used in different environments depending on the average ambient heat in said environment. For instance, if you have a storage facility that needs to be kept at temperatures higher than 135 F, you can imagine why you wouldn't want a orange-bulbed fire sprinkler!
Why does liquid inside a thermometer rise as the temperature s increase?
Most materials expand with the temperature increases. In this case, the liquid in the thermometer expands faster than the glass that holds it.

What is aStandard response fire sprinkler?
Standard response (SR) sprinkler heads are best suited for commercial or industrial buildings, including factories and warehouses. They activate individually to prevent causing water damage where there is no fire present. SR sprinklers take longer to activate than quick response sprinklers, requiring the heat from a fire below to reach a higher temperature before the liquid inside the bulb expands, the glass breaks, and water flows through the sprinkler head. SR sprinklers contain 5 mm glass bulbs that take longer for the expanding liquid inside to burst them. That said, these sprinkler heads still react within seconds, quickly dousing any fire.
What is the proper way of refilling drinking glass?
the proper way of refilling a drinking glass is to pour the liquid into the side of the inside of the glass slowly.
Why does the liquid in a thermometer sink down?
This liquid is sometimes colored alcohol but can also be a metallic liquid called mercury. Both mercury and alcohol grow bigger (expand) when heated and smaller (contract) when cooled. Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold. Its the process of expansion and contraction
Why silver cannot be used in a glass thermometer?
The liquid used in a glass thermometer needs to expand linearly with temperature. It probably does not so it cannot be used. Besides, silver is expensive.
