what substance present in your body balances the atmospheric pressure action on us
If not present (and the intra-alveolar pressure equaled atmospheric pressure) the lungs would collapse.
evaporation
what state of matter is present at the melting point of a substance
No, but a low pressure is.
global warming is the atmospheric condition in the whle world
our blood
* Intensive - Properties that do not depend on the amount of the matter present. ** Color ** Odor ** Luster - How shiny a substance is. ** Malleability - The ability of a substance to be beaten into thin sheets. ** Ductility - The ability of a substance to be drawn into thin wires. ** Conductivity - The ability of a substance to allow the flow of energy or electricity. ** Hardness - How easily a substance can be scratched. ** Melting/Freezing Point - The temperature at which the solid and liquid phases of a substance are in equilibrium at atmospheric pressure. ** Boiling Point- The temperature at which the vapor pressure of a liquid is equal to the pressure on the liquid (generally atmospheric pressure). ** Density - The mass of a substance divided by its volume * Extensive - Properties that do depend on the amount of matter present. ** Mass - A measurement of the amount of matter in a object (grams). ** Weight - A measurement of the gravitational force of attraction of the earth acting on an object. ** Volume - A measurement of the amount of space a substance occupies. ** Length

The atmospheric pressure DECREASES. That's why they supply emergency oxygen masks in planes and why mountain climbers also carry oxygen tanks just in case because it becomes tougher to breath as you ascend. The amount of oxygen present diminishes.
The vapor pressure of a liquid is equal to 1 atmosphere at 100 degrees Celsius, or 212 degrees Fahrenheit. This is because for a liquid to boil, its vapor pressure must rise to reach standard atmospheric pressure, which is about 1 atmosphere. When enough heat is present to do this, the substance will boil.
Amospheric pressure is caused by the weight of air molecules above it. As elevation increases, fewer air molecules are present. Therefore, atmospheric pressure always decreases with increasing height.
When it is bright and sunny outside, it is typically an indication that high air pressure is present. When pressure begins to drop, a disturbance can be near and weather conditions will begin to deteriorate.
This would be moisture buildup present in the air. The high pressure from this would develop over the area, getting conditions ready for the monsoon.
