How would the altitude and the atmospheric pressure of Johannesburg affect the boiling point of water?
The boiling point of water decrease when the altitude increase; the value at Johannesburg is near 94 0C.
The altitude at which rising air reaches the dew point temperature is the?
Lifting Condensation Level
Air pressure is greater at point?
B
What type of cloud has the lowest condensation level?
An approximate value can be calculated by the following expression: Condensation Level (in feet) = [Surface Temperature(F) - Surface Dew Point Temperature(F)]*(1000/2.2) or Condensation Level (in meters) = [Surface Temperature(C) - Surface Dew Point Temperature(C)]*(200) Solution: Dry Adiabatic Lapse Rate (DALR) => -5.5 F/1000 ft of altitude (-1C/100m) Saturated Adiabatic Lapse Rate (SALR) => -3.3F/1000ft of altitude (-0.5C/100m) The SALR is not linear and varies with the initial surface temperature The Level of Condensation will occur at the altitude where the Air Temperature is equal to the Dew Point temperature at that altitude. Setting the two equations equal to each other will give an approximate value. TA: temperature at altitude; TS: temperature at surface; DA: dew point temperature at altitude; DS: dew point temperature at surface TA = TS-(5.5F/1000ft)*altitude or TS-(1C/100m)*altitude DA = DS-(3.3F/1000ft)*altitude or DS-(0.5C/100m)*altitude Setting TA = DA and rearranging quantities gives the equations given above The level of condensation derived by the above method will only yield an approximate value.
What happens to the density of air as you go further below sea level altitude but in dry land?
Density always increases as altitude decreases. So the air density below sea level will be greater than the air density at sea level.
Is the altitude greater at the top of a mountain?
A mountain top is higher (greater) in altitude. That is the definition of altitude : height above a surface, or above sea level.
Does melting point and boiling point of liquid changes from altitude to altitude?
The boiling point depends on altitude (pressure). The effect on the melting point is not significant.
Is altitude greater at sea level?
No it is not
How does altitude in the atmosphere affect air pressure?
The greater the altitude, the lower the air pressure.
Is the temperature cooler in low altitude or higher altitude?
There is ever-so-slightly less... but good luck measuring that tiny difference!Altitude is the point at which an item sits in relation to sea or ground level.
What would be the boiling point of alcohol at a higher altitude?
it depends on the altitude
Is air pressure greater at high altitudes or low altitudes?
It is greater at a lower altitude.
Does melting point change from altitude to altitude?
The melting point of a substance does change with altitude. All due to atmospheric pressure, makes different elements behave differently.
How high is a mountain?
Attending an altitude greater then that of a hill,a mountain is usually about greater than 2000 ft. (610m)Note that this does not necessarily mean altitude above sea level.
Does melting point changes from altitude to altitude?
Yes, it does. It is do because with change in altitude their is change in temp. and pressure which also changes the melting point. The change in melting point could be small to large depending upon change in conditions at different altitudes.
How are melting and boiling points affected as altitude is increased?
Boiling point decrease at high altitude.
What is the altitude of the north point?
Sea Level.
