Well atmospheric pressure changes with elevation and has to due with weight of air. The weight of air depends on it's constituents. Pollutants can change the weight but it's so small it is negligible.

What temperature does water evaporate and what temperature does water freeze?
in atmospheric pressure water evaporates at 100 degrees Celsius and freeze at 0 degrees Celsius. This may vary based on pressure
Denver atmospheric pressure in mm Hg?
Varies from day to day (actually, moment to moment). If you want the pressure on a particular day, a local branch of the NOAA/NWS may be able to answer that.
Does the temperature of the water change the boiling point?
The boiling point of water depends only on pressure, not ambient temperature. The only correlation between climate temperature and boiling point would come about from the fact that cold climates in temperate parts of the Earth are usually at higher elevations than warmer climates and therefore have lower atmospheric pressure.
Why do scientists think mars may have once been a warmer place and may have had a thicker atmosphere?
Scientists have proven that liquid water once existed on Mars. Currently Mars is too cold and atmospheric pressure is too low for water to remain liquid, so both temperature and surface pressure must have been higher.
How does hot and cold air pressure effect temperature?
To fully answer this, we would need to know if we are talking about a contained pressure (like in a tire) or atmospheric pressure. If a tire is filled with a specific pressure at room temperature, the pressure would increase as the temperature increased. Likewise, if the temperature was cooler, the pressure in the tire would decrease. As for atmospheric pressure, we may have to limit this question to an example since the air around us is always moving. If we could make a 1 square inch (at the end) tube that stretched from the surface of the Earth to outside of the atmosphere, we would have 14.5 pounds of air at sea level. If this air was heated and did not flow out of the tube, it would weight the same, just take up more space.
What gauge measures both vacuum and pressure?
Gauge pressure usually refers to the pressure difference between ambient, atmospheric pressure and the pressure in a vessel or line. A gauge pressure of zero would mean that the vessel or line was at atmospheric pressure. Normally the pressures of interest are ABOVE atmospheric so the gauge pressure is positive. Vacuum gauge pressure measures how far BELOW atmospheric pressure a vessel or line is. As such vacuum gauge pressure may be measured as a negative number - or for convenience it may be reported as a positive number with the caveat that it is "vacuum gauge pressure", meaning that the reported pressure is how far atmospheric pressure is above the pressure in the vessel or line.
What is an atmospheric disturbance?
An atmospheric wave is a periodic disturbance in the fields of atmospheric variables like surface pressure or geopotential height, temperature, orwind velocity) which may either propagate
Why are barometers important in life?
Advance warning of changes in atmospheric pressure can tell us what may happen with the weather. Example: a drop in atmospheric pressure indicates a storm of some kind is on its way.
Defined as the point as which liquids vapor pressure equals the atmospheric pressure?
The normal boiling point(also called the atmospheric boiling point or the atmospheric pressure boiling point)is the temperature at which the vapor pressure of a liquid equals the atmospheric pressure at sea level, 1 atmosphere.The normal boiling point of water is about 100 degrees Celsius at a pressure of 1 ATM (i.e., 101.325 kPa).General Useful Information:The boiling point of a liquid is the temperature at which the vapor pressure of the liquid equals the environmental pressure, but the environmental pressure may or may not be equal to the atmospheric pressure at sea level, 1 ATM.If the surrounding environmental pressure is less than atmospheric pressure, then the boiling point is less than the normal boiling point.If the surrounding environmental pressure is greater than atmospheric pressure, then the boiling point is greater than the normal boiling point.At the boiling point, adding enough heat to the liquid will cause the liquid to vaporize (that is boil or form a gas).
What are the two types of outside pressures that may act on the outside of an organism?
Atmospheric pressure out side the body and hydrostatic pressure for animals that live in water
What is the difference between pressure and atmospheric pressure?
Atmospheric pressure is a unit of measument, and measure the pressure of the air. Much like the deeper you go in the ocean the higher the pressure is. You are actually on the bottom of an ocean of air, the higher up the less atmospheric pressure and eventually there is non when you reach outer space.

Why does nose starts bleeding on high mountains?
at high altitudes,since the air pressure is less,breathing becomes difficult and nose bleeding may occur due to excess pressure of blood over the atmospheric pressure.
How often do the bulbs need to be changed in a tanning bed?
If you have a high pressure tanning bed bulb, it will need to be changed after about 1000 hours of use. Low pressure bulbs may need to be changed as frequently as every 600 hours.
Is there any change in mass of reactants and products of copper carbonate and hydrochloric acid?
No, there is no change Everything reactions possible follows the law of conservation of mass If u did it practically and u didn't get the exact mass.. There may the weight of apparatus or atmospheric pressure included
Why can't we feel the atmospheric pressure?
We do not feel the earths atmospheric pressure because it is the same everywhere all round us. The body can only really feel pressure differences. Try this, put your finger in your mouth and suck. Your finger and indeed the inside of you mouth will feel the pressure difference you create. Also sometimes if you go up in a lift or are in a car, bus or plane that goes up or down, you may feel pressure changes in your ears. This is because the pressure in your middle ear takes time to equalize with the atmospheric pressure changes caused as you go up and down in altitude.
