How does the thermometer work to measure temperature accurately?
A thermometer works by using a substance, like mercury or alcohol, that expands or contracts with temperature changes. This substance is contained in a sealed tube with markings to show the temperature. When the temperature rises, the substance expands and moves up the tube, indicating a higher temperature. When the temperature drops, the substance contracts and moves down the tube, showing a lower temperature. This allows the thermometer to accurately measure temperature changes.
What is altimeter made from?
A sealed bellows that expands and contracts depending on the ambient pressure.

Why did the sealed chocolate chip bag expand in your freezer?
Just like water expands to ice..
Why is it dangerous to heat a sealed or presssurised can?
heat causes any substance to expand. If enough heat is applied to change a substance from a liquid to a gas, it expands exponentially. In a sealed or already pressurized can, this can cause pressure to build until the can cannot contain it any more and explodes like a bomb. This can send shrapnel from the can flying a good distance, and can cause serious injury if it hits anyone.
What is in the sealed can in an aneroid barometer?
The sealed can in an aneroid barometer typically contains a small amount of air (or sometimes a vacuum) that contracts or expands with changes in atmospheric pressure. This movement of the sealed can is what causes the barometer to measure and display changes in air pressure.
Would the boiling point of water be higher or lower on a mountain peakhow would the boiling point be affected in a pressurized system?
The higher the pressure being exerted on the water, the lower the boiling point becomes. Yes the boiling point is affected in a pressurized system. If you put water in a sealed container and kept raising the pressure it will eventually reach it's boiling point without the need of adding heat.
If the pressure in a sealed container is reduced can boiling point of a fluid be also reduced?
Yes. You can, for example, boil water at room temperature if you apply a vacuum pump to the container. However, if it was ONLY a sealed container (reduce the pressure and then take the vacuum pump away), the vapor increases the pressure and the whole thing comes to equilibrium and stops boiling.
How does a thenometre work?
A thermometer works by measuring temperature using a material that expands or contracts with changes in temperature. This material is usually mercury or alcohol sealed in a glass tube. As the temperature changes, the liquid expands and rises in the tube, providing a visual indication of the temperature.
Why do tin cans get crushed if cooled after heated and closing is mouth?
Assuming the can can be sealed. When the can is heated the air inside it expands. If the can is then sealed and allowed to cool the air inside contracts which causes the pressure inside to drop. Because the outside air pressure is now greater it crushes the can.
What is the density of a substance in a sealed 25000 CM flask that is full to capacity with 3600 G of a substance?
The density of the substance in the flask is 1.44 g/cm^3 (3600 g divided by 25000 cm^3).
What is the measurement of theormeter?
A thermometer is used to measure temperature by the movement of a substance called mercury inside a sealed tube
