Because Mercury expands in heat, it is more accurate than other elements used in thermometers.
What else can I help you with?
Which thermometer is a greater health hazard if it breaks Is it the mercury in glass or alcohol in glass thermometer?
Mercury in glass thermometers pose a greater health hazard if broken, as mercury is a toxic substance that can be harmful if inhaled or ingested. Alcohol in glass thermometers are considered less hazardous as alcohol is not as toxic as mercury. It is still important to clean up any broken thermometer carefully to avoid injury.
How are thermometer made?
It generally made using fluid which expand or contract linearly with temperature such as mercury, water or alcohol. Electronic thermometer use the relation of thermal property effect electrical conduction difference to measure temperature.
Why are the properties of Aluminum always the same while the properties of the lead - glass may vary?
The properties of aluminum are consistent because aluminum is a pure element with a uniform atomic structure. Lead-glass, on the other hand, is a composite material made up of lead and glass, which can vary in composition and texture, leading to different properties. The variations in lead-glass properties stem from differences in the ratios of lead to glass and the manufacturing process.
What is the importance of thermometric liquids?
Thermometric liquid is the liquid found in the thermometer that help in the up and down movement of the temperature.
Which part of the CNS is made up of the midbrain pons and medulla and oblongata?
The brain stem.
How does a glass stem thermometer measure temperature?
A glass stem thermometer measures temperature by using the principle of thermal expansion. The liquid inside the glass stem expands or contracts with temperature changes, causing the level of the liquid to move up or down the scale. This movement indicates the temperature.
Why is the stem of thermometer made up of glass?
Glass is chosen for thermometer stems because it is transparent, allowing easy observation of the liquid inside. Glass is also chemically inert, resistant to thermal expansion, and can be easily calibrated for accurate temperature readings. Additionally, glass is non-reactive with most substances, ensuring that measurements are not affected by the material of the stem itself.
Why a mercruy in a glass thermometer holes up a uniform stem?
because it is cheap and it does not expand on heating therfore it doesnt break
Why does the substance in the thermometer stem rise up?
The substance in the thermometer stem rises up because it expands when heated. This expansion is due to the particles within the substance moving more rapidly and spreading further apart, causing the substance to take up more volume and rise up the stem of the thermometer.
Explain how an ordinary glass fever thermometer is designed?
An ordinary glass fever thermometer is typically made of a sealed glass tube filled with mercury or dyed alcohol. It has a calibrated scale along the length of the tube to measure temperature. When the thermometer is placed in contact with a warm object, the temperature causes the liquid inside to expand and rise up the scale, indicating the temperature value.
What should you not do while using a glass thermometer?
shove it up ur ASSS
What is thermometer made up of?
In this answer I m referring to the normal thermometers. Not the electronic thermometers. There is a very very thin capillary tube incide the thermometer which is filled with mercury and it has a bulb aT one end. When it touches a surface, the mercury expands, rises in the capillary and the temperature is shown.
Which thermometer is a greater health hazard if it breaks Is it the mercury in glass or alcohol in glass thermometer?
Mercury in glass thermometers pose a greater health hazard if broken, as mercury is a toxic substance that can be harmful if inhaled or ingested. Alcohol in glass thermometers are considered less hazardous as alcohol is not as toxic as mercury. It is still important to clean up any broken thermometer carefully to avoid injury.
Why are the thermometers called liquid in glass thermometers?
A so-called "glass" thermometer has a small bore-hole in the center of the glass that has some liquid in it. It's the activity of the liquid in the narrow hole that makes the thermometer a thermometer.
Who invented the water thermometer?
Charles WingerThe Thermometer was invented by Galileo Galilei in 1593. His thermometer consisted of water in a glass bulb; the water moved up and down the bulb as the temperature changed.
What is a fiber made up made up of?
It's made of glass.
What makes a liquid in glass thermometer sensitive to a small changes in temperature?
As the temperature rises or falls the liquid in the reservoir (bulb) of the thermometer rises or falls ) the liquid expands (heats up) or contacts (cools off). The volume change is made visible in the capillary (tube) in the part of the thermometer with the scale. This is the only part of the thermometer into which the extra volume and expand.Increasing the volume of fluid or decreasing the diameter of the capillary makes the changes more apparent/
