Why are thermometers made with alcohol instead of water?
thermometers are made out of mercury and alcohol because mercury expands when it is heated
Is mercury being heated to produce mercury vapor a physical change?
YES, because evaperation is the same as changing it in to a gas which is a physical change.
How is element mercury purified or extracted?
Mercury is extracted from cinnabar by heating and collecting the vapors. In factories, the rock is ground up into a fine powder which is then heated.
What liquid expands when heated?
All liquids expand when heated. e.g. Mercury in a thermometer. One exception may be water when heated form 0 to 4 degrees Celsius.
Is mercury able to be heated up?
Yes, mercury can be heated up. Heat energy will cause mercury atoms to move more and spread out. This is actually how old thermometers would work. The higher the temperature, the more the particles would move and the more the liquid would expand. This would fill up the glass tube on the thermometer and make it possible to tell the temperature.
When heated mercury oxide produces oxygen plus mercury what would be the combined mass of oxygen and mercury if 20g of mercury oxide were heated?
If 20g of mercury oxide were heated, the combined mass of oxygen and mercury would be 20 grams.
When Mercury oxide is heated it forms?
When Hg2+ (mercury oxide) is heated it creates both Hg (liquid mercury) and O2 (oxygen gas)
If the substance is warmer then the Mercury in the thermometer the Mercury will?
If Mercury (element) is heated then like every other substance it expands.
Why is Mercury in thermommeters?
mercury is a liquid metal that when heated can determine tempreture in thermometers
What is the word equation for solid mercury two oxide breads down when heated forming the elements mercury and oxygen?
Mercury+Oxygen----> Mercury Oxide
Does mercury catch fire when heated?
no
What would be the combined mass of the released oxygen and mercury if 20g of mercury oxide were heated?
10
Why mercury is heated faster than water?
in mercury the molecules are closser with respect to the molecular structure of the water. so when both of them are heated , there will be more molecular collision in mercury than in water. that's why , when both of them are heated to the same extend mercury produces more heat than water.
Mercury oxide is heated to form oxygen?
A chemical reaction happens when mercury is heated and reacts with oxygen. This reaction results in the creation of mercuric oxide, an orange or red compound.
Why are thermometers made with alcohol instead of water?
thermometers are made out of mercury and alcohol because mercury expands when it is heated
Is mercury really hot and really cold?
The side of Mercury that faces the sun is extremely heated, however the side of Mercury that faces away from the sun is extremely cold.
When a mercury therometer is heated the mercury expands and rises in the thin tube of glass What does this indicate about the relative rates of expansion for mercury and glass?
It indicates that the mercury expands much faster in reaction to change in temp. If the glass expanded at the same rate as the mercury does, the level of mercury would not change.
