Barometer is a scientific device. It is used to measure air pressure in environment. Air pressure changes with distance upper and bottom sea level.
Barometer is also used for measure altitude.
Barometric pressure has main effects on water and atmosphere conditions.
Hence, Barometer is used to measure air pressure.

Physical and chemical breakdown of rocks
<span>There are a number of ways
to express concentration of a solution. This includes molarity. Molarity is
expressed as the number of moles of solute per volume of the solution.
Calculations are as follows:
Molarity of NO3 ion = 32.0 g Mg(NO3)2 ( 1 mol / 148.3 g ) ( 2 mol NO3 / 1 mol Mg(NO3)2) / .425 L
MOlarity of NO3 ion = 1.02 M </span><span>

Answer:
Water heaters must have vent to the outside of the heater to remove exhaust air from the water heater, the vent go directly through it walls. It is likened to the vent in natural gas water heater which have a vent to the outside that remove by products of combustion and can also bring in air combustion.
The edifice from the hot water vent are made of metals or plastic materials depending on the venting systems.
It's most likely to bond with chlorine.
