High pressure is associated with fair dry weather and Sunshine.
the melting point decreases as pressure increases, so the further into the earth feldspar is pushed, the higher the pressure and the lover the melting point
The boiling point is that temperature when the SATURATEDvapor pressure of a liquidbecomes equal tothe surrounding pressure.Thus the higher the sorrounding pressure, the higher the boiling point.
Air pressure also affects the boiling point of water. The higher the air pressure, the higher the boiling point.
Air pressure on earth results from the earth's gravitational pull on the earth's atmosphere. In some sense, pressure results from the weight of the air above the point at which one measures pressure. At higher altitudes, there is less air above, resulting in less weight, which translates into pressure.
As a person climbs to a higher point on earth, the air pressure decreases because there is less air above you. ... The phenomenon is called "hydrostatic equilibrium".
Dry air is more dense than moist air because water vapor is lighter than the two main gases found in air, nitrogen and oxygen. The pressure of a gas depends on both its temperature and density, therefore, dry air would create more pressure than moist air, at a constant temperature.
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.
as you go higher above sea level, pressure decreases. Due to the decrease in pressure, the temperature needed for water to boil is less than it is than it would be at sea level. Thus, it would take less heat energy for the bonds to break and become a gas than it would in an environment with more pressure.
Putting a substance under pressure increases its melting point because substances expand as they melt. Putting them under pressure makes it harder for them to expand, which means that they require more energy (heat) in order to transition from a solid state to a liquid state. If a substance is under pressure, decreasing the pressure will lower its melting point.
The melting temperature of materials is dependent on the pressure that is applied, whereby the higher the pressure, the higher the melting temperature. As such the rocks in the mantle are experiencing such a high pressure, that their melting point is driven up beyond the temperature within the Earth's mantle so they remain solid.
Higher pressure increase the boiling point of gasoline, just like with water.
in lowland the atmospheric pressure is higher so the boiling point will be higher,in highland atmospheric pressure is low so the boiling will be low
