Mercury is having a higher specific density ( about 13 times that of water) . So if we want to make a barometer using water it should be at least 13 times the length of mercury barometer that is about 11m so it is advisable to use mercury as a barometric liquid.

Why water is unsuitable as a barometric liquid?

Water is unsuitable as a barometric liquid because it has a high vapor pressure, which can lead to evaporation or leakage in barometers. Additionally, water freezes at 0°C and boils at 100°C, which would limit the range of pressures that can be measured accurately. Finally, water can also corrode the equipment used in barometers.


What does barometric pressure have to do with evaporation?

Above the surface of liquid water is a layer of water vapor. It has pressure. The atmosphere also has pressure. It pushes against the water vapor. The water vapor pushes against the atmosphere. It is called vapor pressure. It is related to temperature. When the vapor pressure equals barometric pressure, water boils. Normally this occurs at 100C or 212F. If you reduce the barometric pressure, you can reduce the boiling point of water. So when the barometric pressure is lower, the water vapor above the water has an easier time mixing with the atmosphere. As it mixes with the atmosphere, it is replaced by vapor from the water. It evaporates.


What effect would a decrease or increase in barometric pressure have on the boiling point?

If you were to travel to Denver, the mile high city, air pressure is reduced. This makes it easier for gas molecules to escape the liquid, hence the boiling point lowers. On the other hand, when pressure increases, gases have a harder time escaping the liquid so the boiling point must increase.

What was the Mercury barometer used for?

The mercury barometer is a tool used by meteorologists and other scientists to find the air, or "barometric" pressure. Because mercury is liquid at room temperature, it can change shape due to changes in the atmosphere. Earth's barometric pressure is characterized as the downward force of air on the surface of Earth. If mercury is placed in a tube and the level decreases by a huge increment, it would show an increase in barometric pressure. Mercury barometers can also be used to detect incoming storms as right before a storm, the air pressure decreases drastically.

What is a barometric trend?

A barometric trend refers to the direction in which atmospheric pressure is moving over a period of time. It can be rising, falling, or holding steady. Monitoring barometric trends can help predict short-term weather changes and is often used in weather forecasting.


Why is a condenser called a condenser?

The reason why it is called a barometric condenser is because it makes contact and it is a long vertical pipe into which it condensates and cools the liquid flow to accomplish the removal of pressure. It is also stated that when the pump is used the system is called a low level barometric condenser.
