Largest Peninsulas of World : Arabian Peninsula. Arabian Peninsula or Arabia is the largest peninsula of world which occupies an area of 3.2 million square Km. It is located in middle east and comprises of 7 countries including Saudi Arabia, Oman, Yemen, UAE, Kuwait, Bahrain and Qatar.
Pressure is merely force per area, so if the force increases but the box stays the same size, the pressure has increased. Air density can decrease with temperature if pressure is also decreasing. If pressure is constant, this cannot happen (they would be inversely related). Any time you specify a relation between any two of pressure, density or temperature you must hold the third constant or specify its behavior.
1 Low and High Air Pressure. 2  Low air pressure= less weight pushing down= air is rising and cooling which helps form clouds. 3  High air pressure= more weight pushing down= air is sinking and warming with less humidity.4  Falling or Low Barometric Pressure.verage Sea-Level pressure: 101.325 kPa /1013.25 mbar / 760 mmHg / 29.921 inHg. Pressures seldom increase or decrease 1 inch of mercury (3.386 kPa /33.86 mbar / 25 mmHg) above or below the 30 inch mark (101.591kPa / 1015.91 mbar / 762 mmHg) unless weather conditions are extreme.
