Does mercury exert more pressure than water?
mercury exerts more pressure than water bcause mercury is a metal and water is a non metal obviously mercury weighs more than water
How does mercury outboard water pump work?
A Mercury outboard water pump is a engine cooling system. A outboard water pump is what blows steam through to get the car cool,
URGENT why do you use mercury in barometers and not water?
At lower temperatures water will freeze and mercury will not.
Where is the water pump in a Mercury Mountaineer1999?
The water pump is bolted to the front of the engine behind the engine cooling fan
What do you look under for water resivior for cooling 2002 mercury sable?
On a 2002 Mercury Sable : The engine coolant reservoir is at the front of the engine compartment , on the passenger side of the engine compartment ( the engine coolant reservoir has a thread on cap on it , that is your pressure cap / radiator cap )
Ford F350 diesel what caused water is in the oil and oil in the water?
does cooling system hold pressure?
In a pressurized water reactor the primary cooling water is?
In a pressurized water reactor the primary cooling water is under pressure of around 150 atm and its inlet temperature around 320 degree centigrade.
Why water cannot be used in simple barometer?
Following are the reasons why mercury and not water is used in a barometer:1. Mercury is relatively denser than water, consequently the length of the column of water would have to be about 34 feethigh to exert pressure equal to that of the atmosphere while the column of mercury need to be only 30 inches to exert pressure equal to that of the atmosphere.2. Mercury has a very low vapor pressure when compared to that of water. So it is more sensitive than water to the changes in the atmospheric pressure and rises more quickly to record the changes in the atmospheric pressure.3. Mercury's freezing point is much lower than that of water's so it can record the atmospheric pressure at temperatures below that of 0 degrees centigrade.4. Mercury does not evaporate easily so very little mercury vapor enters the vacuum above the mercury in the tube.5. Mercury being a metal shines brightly and so can be used to read the markings on the tube easily.
Would expect pressure exerted by water to be greater or less than the pressure exerted by the same amount of mercury?
if you were to immerse yourself under a meter of mercury the pressure experienced would be greater than if you were to immerse yourself under a meter of water.
Does water vapour contract when cooled?
Yes. Cooling down water vapour removes energy. Pressure is a direct measurement of energy density (units for pressure: N/m2 which is the same as Nm per m3). So removing energy from water (thus cooling it) would lower its energy density, decreasing its pressure. Pressure directly influences volume, and so reducing pressure will reduce volume.
Why is mercury preferred to alcohol in barometer?
Mercury has a very low vapor pressure. Vapor pressure is the pressure exerted by the gaseous form of a liquid on the liquid itself when both states are in equilibrium. A higher vapor pressure means (which is known as a volatile substance ← [this statement is unclear and seemingly unrelated. I cannot determine its relevance, but perhaps it can help you]) more pressure is exerted by the ambient atmosphere on the liquid and hence it cannot rise easily to denote the pressure increase. Hence liquids with low vapor pressure are usually preferred as they can rise easily or they can show more sensitivity. Water has a relatively high vapor pressure, and thus is not as sensitive to changes in pressure as mercury is.This is why when we measure pressure with water, we divide the water level change by 13.6, which is the ratio of the density of HOH to the density of Hg. Our answer changes from the non-standard pressure measurement in milimetres of HOH to the commonly-used milimetres of HgFollowing are the reasons why mercury and not water is used in a barometer:1.

Why is it mercury rather than water used in barometer and in blood pressure measurements?
A water barometer would have to be many feet tall because the density of water is much lower than that of mercury. In addition, the vacuum above the column would be spoiled by the water vapor pressure, far higher than that of mercury, and strongly temperature dependent.
