A substance that expands faster will also contract faster. Alcohol expands more than mercury because of its low density and volatile nature. … Mercury thermometers can be used to measure higher temperature than alcohol thermometers because of its high boiling point.
Does mercury expand faster than alcohol?
Mercury has a greater coefficient of thermal expansion than alcohol. This means a column of mercury will expand and rise more than a column of alcohol for the same temperature change.
Does mercury expand quickly?
It is a metal, so it’s a good conductor of heat. This means that it reacts quickly to changes of temperature. It expands evenly with temperature, so a linear scale can be used with quite a high degree of accuracy.
Which liquid expands most between alcohol mercury water?
Conclusion: ⇒ Ethanol will expands 6 times faster than Mercury under similar liquid conditions.
What expands more than mercury?
Alcohol expands more than mercury.
Does mercury expand uniformly?
It expands uniformly on heating. The specific heat capacity of mercury is low. The boiling point of mercury is high (357∘C) and the melting point of mercury is low (−39∘C).
Does mercury expand more than water?
Therefore water has minimum volume at 4C and hence maximum density which is slightly higher than 1 g/cm3. Above 4C, water expands like any other liquid.
|Good thermal conductor||Poor thermal conductor|
|Has regular expansion||Has a slight irregular expansion|
|Does not wet the glass||Wets the glass|
What expands mercury?
The expansion occurs because the atoms in a material vibrate more strongly as you add heat energy to them; as the vibrations increase, the average distance between atoms also increases.
Does mercury expand and contract?
When heated or cooled, mercury expands or contracts at a rate that is more constant than most other substances. Also, it has a wide range of temperatures between its boiling and freezing points.
What is alcohol expansion?
The expansion of alcohol in a thermometer is one of many commonly encountered examples of thermal expansion, the change in size or volume of a given mass with temperature. … The greater the temperature change, the more a bimetallic strip will bend.
Why does alcohol expands more than water?
If equal volumes of water and alcohol are heated to the same rise of temperature, then alcohol will expand more than water because coefficient of real expansion of alcohol is more than that of water. Two iron rods – one 10 m long and the other 5 m long, are heated to the same rise in temperature.
What expands more alcohol or water?
alcohol expands more than water.
Does mercury expand on heating?
Mercury, like almost all matter expands as it is heated.
Why does alcohol expand more than mercury?
Alcohol expands more than mercury because of its low density and volatile nature. Mercury thermometers have the advantage of being small and compact due to its low expansion. … Alcohol thermometers can be used to measure lower temperatures than mercury thermometers.
Does alcohol expand linearly?
It has a very linear rate of expansion — meaning that it’s going to expand almost exactly the same distance going between 30F – 40F as it is between 200F – 210F. With many other liquids, you’d need to have markings on your thermometer that get wider and wider apart as you move up the scale.
Why does alcohol expand?
Does alcohol constrict blood vessels or cause them to expand? … At levels of initial intoxication, alcohol works as a vasodilator, causing blood vessels to relax and expand. However, at extremely high levels, alcohol works as a vasoconstrictor, causing veins to tighten and constrict.
