Illustrate and label the parts of hydrometer?
An instrument used to measure the Specific Gravity (or Relative Density) of a liquid is called as a Hydrometer. It is the Ratio of the density of the liquid to the desnity of the fresh water (i.e. 1.000). The instrument consist of a glass chamber with Lead Shots or Mercury filled at the bottom or the base, to make it float upright.
How is the measurement of density of liquids possible?
A hydrometer is an instrument used to measure the specific gravity (or relative density) of liquids; that is, the ratio of the density of the liquid to the density of water.A hydrometer is usually made of glass and consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float upright. The liquid to be tested is poured into a tall container, often a graduated cylinder, and the hydrometer is gently lowered into the liquid until it floats freely. The point at which the surface of the liquid touches the stem of the hydrometer is noted. Hydrometers usually contain a scale inside the stem, so that the specific gravity can be read directly. A variety of scales exist, and are used depending on the context.Hydrometers may be calibrated for different uses, such as a lactometer for measuring the density (creaminess) of milk, a saccharometer for measuring the density of sugar in a liquid, or an alcoholometer for measuring higher levels of alcohol in spirits.
Is mercury heavier than copper?
Yes ..mercury ie heavies then lead
Which metal you could boil in a Bunsen flame?
lead
Is mercury hot enough to melt lead?
If you mean the chemical element Mercury, then no; mercury and lead are separate elements. At high enough temperatures, they can be melted together, but because mercury is liquid at room temperature they probably wouldn't stay combined.If you mean whether the planet Mercury contains the element lead, then the answer is that it almost certainly does. The core of Mercury is dense and metallic, and lead (like all elements up through uranium) was present at the formation of the solar system.
Why mercury is used in hydrometer?
A hydrometer consists of a cylindrical stem and a bulb weighted with mercury or lead shot to make it float upright. Mercury has a higher density, thus a lower volume for the same weight than lead. It is a toxic liquid metal, but also more dangerous and difficult to clear up the mess when a glass hydrometer is broken

Why can't you extract lead from lead oxide but you can with mercury and mercury oxide?
actually you can still extract lead from lead oxide, but you need to do this experiment with carbon or other reducing agent e.g. hydrogen and with a high temperature Celsius. But the reason that you can extract the mercury from the mercury oxides exactly is the higher reactivity of the lead. higher the reactivity means more difficult to extract the metals from the ore. so it is possible for lead to extract it from the lead oxide
What does mercury and lead chloride make?
Both lead and mercury are metals, physically lead is solid at room temperature, however mercury is a liquid, but chemically they are both metals. Mercury is a classified as a transition metal, however technically isn't as it doesn't not have a partially filled d-orbital in either it elemental state or as one of it's common ions. Lead on the other hand belongs to the group known as the poor metals.
How can the density of a hollow lead ball filled with water be increased?
The density of a hollow lead ball filled with water can be increased by adding a denser material, such as mercury, into the ball. This will increase the overall mass of the ball without significantly increasing its volume, thus increasing its density.
Is most pencil filled with lead?
Some pencil's are filled with lead, but rarely any nowadays. Pencils use to be filled with lead, but now pencils are typically filled with graphite as lead is poisonous to humans.
Does lead float or sink in liquid mercury?
Lead will sink in liquid mercury because lead is denser than mercury. Mercury is a heavy liquid metal, so most metals will sink when placed in it.
Is mercury the lightest substance in between aluminium lead and copper?
At "normal" temperatures, Mercury is denser than any of those substances ... slightly more so than lead, somewhat more so than copper, and a lot more so than aluminium.
If you drop a piece of lead into a pool of mercury will it sink or float?
Lead would float in mercury, as it is slightly less dense. (11.3 g/cc for lead, 13.5 g/cc for mercury)
Is Mercury heavier than Lead?
Atomically, no. Mercury's atomic weight is 200.59 whereas Lead's atomic weight is 207.2. So basically, if you had the exact same amount of Lead and Mercury, lead is heavier.

Which has a larger volume a liter of water or a liter of mercury?
Oh, dude, a liter is a liter, whether it's filled with water or mercury. Like, it's a unit of volume, not some magical potion that changes size based on what you pour into it. So, yeah, a liter of water and a liter of mercury have the same volume, my friend.
