There are few reasons <span>why mercury is used in liquid barometer instead of water:
1. </span>Mercury (13.69 g/cm³) is more dense than water (1.00 g/cm³), so if we use water in barometar, <span>length of barometer would be much longer.</span><span>
2. </span><span>Mercury has lower vapor pressure than water.
3. </span>Mercury has lower freezing point (-38.83°C) than water (0°C)<span>.

<span>Our Earth is structured around the densities of the materials which make it up.One property of density is that it determines the way materials in a mixture are sorted. This property of matter results in the layering and structure of Earth's atmosphere, water, crust, and interior.</span>
