The lower the pressure then the lower the temperature that is required to make it boil. Water at the top of Mount Everest boils well below 100 degrees centigrade due to the lower atmospheric pressure.
There is a direct relationship between the temperature at which water boils and the air pressure on it. Higher pressure, higher boiling point. Lower pressure, lower boiling point.
for this question the answer is in the ideal gas equation
PV = nRT
the pressure(P) is directly proportional to the temperature(T)
Water in the air doesn't heat the air up. Water in the air moderates temperatures. It tends to make daytime temperatures cooler and nighttime temperatures warmer than they would be in drier air.
it doesn't
As temperature increases so does the pressure
Think of it this way, if you had a plastic bottle filled with water and you poked a hole in the side, would water squirt out or would air squirt in? If air squirted in, then the air pressure would have to be higher. But since we know that the water would squirt out, we know that the water's pressure must be stronger. Of course, this is under normal conditions. If you pumped the air pressure up enough, then the air pressure may become stronger than standard water pressure. So actually, water pressure is generally stronger than air pressure.
Warmer air has higher saturation mixing ratios then cold air does. So therefore because of this 100% humidity in cold air is not 100% humidity in warmer air. The warmer the temperature, the more water vapor in the air. The colder the temperature, the less water vapor in the air.
Cold temperatures increase air pressure.
Three factors that affect air pressure are temperature, altitude, and water vapor.

In most cases, the water temperature only affects land temperatures when the land is in relatively close proximity to the water. The winds will flow accross the warmer water and carry the radiated heat over the land closest to the shoreline. As the wind blows further inland, the affects of the water are slowly dropped off. In contrast, the air temperatures can SLOWLY affect the water temperatures. Over time, cooler/warmer air temps will cool/warm the waters if the temps are fairily consistent for a period of time. The larger the body of water, the longer it takes for the air to affect it.
Oceans affect climates by slowing the rise and fall of air temperatures. Because water has a high specific heat, it holds heat longer than air.
Water boils at lower temperatures at higher altitudes because the atmospheric pressure is lower. In a valley, the air pressure is greater, which allows water to reach a higher temperature before boiling. At higher altitudes, where the air pressure is lower, the boiling point of water decreases.
rising warm air creating low pressure cells rising warm air creating high pressure cells falling air temperatures creating low pressure cells falling air temperatures creating high pressure cells
High temperatures coincide with low pressure and low temperatures coincide with high pressure. Cold air is heavier than warm air and has a higher pressure with it.
temperature (heat), volume, water vapor, and altitude (how high or low it is) all affect air pressure
Water Vapor affects pressure because moist air contains many heavy gases such as O2,N2 etc. But less water vapor. Since these gases are heavier than water vapor, it becomes more dense constituting more pressure. So Moist air contains less pressure than Dry Air.
Atmospheric pressure systems are made of air.
There is a direct relationship between the temperature at which water boils and the air pressure on it. Higher pressure, higher boiling point. Lower pressure, lower boiling point.
