more mountains + more air equals more pressure.... its like sitting on a bag of air
Temperature, pressure, and common ion effect
Changes in both temperature and pressure induce phase changes in water (and all other materials!).
Water boils faster in the mountains because the air pressure is lower at higher altitudes. Lower air pressure reduces the boiling point of water, causing it to reach boiling temperature faster than at sea level where air pressure is higher.
temperature, water vapor, and elevation.
Temperature, salinity, and pressure have significant effects on water density. As temperature increases, water density decreases because warmer water molecules are more spread out. Higher salinity increases water density since dissolved ions make the water heavier. Pressure also impacts density, with deeper water being denser due to the weight of the overlying water column.
Evaporation increase with the increase of temperature.
gas composition of atmosphere (including water vapour); altitude; temperature; and wind velocity.
Vapour rom the boiling water is not allowed to escape and so the pressure above the water increases. This raises the temperature at which the water inside the cooker boils.
The effect of negative pressure or vacuum, lowers the boiling point of fluids. Water will boil at room temperature in a vacuum. Automotive cooling systems are pressured to achieve the opposite result of raising the boiling temperature.
It is the effect of air pressure. The air pressure at the top of a mountain is less than the air pressure at sea level. The effect of air pressure on a water surface is to prevent or oppose water molecules escaping from the surface. The greater the air pressure, the more heat energy is needed to allow the water molecules to escape and so at sea level the water will boil at a higher temperature than if it were on top of a mountain.
Temperature does have an effect on water's phase. When the temperature of water is below 0 degrees Celsius, it freezes into ice. When the temperature is between 0 and 100 degrees Celsius, it remains in liquid form. Above 100 degrees Celsius, it vaporizes into steam.
Latent heat of water is the heat required to change its state at a particular temperature BECAUSE of the pressure at which the water is at at the point of fusion or evaporation.The latent heat is not affected by temperature (in fact there is no temperature change during absorption of latent heat) it is affected by the pressure acting on a substance. As the pressure increases, the latent heat (of evaporation) decreases, consequently with the change in pressure there is also a different temperature at which the evaporation takes effect, higher pressure, higher temperature at the evaporation point.
