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.
With density being the ratio of mass per volume, the gas density of the balloon thus varies only with its volume (when mass is held constant). If we squeeze the balloon, we compress the air and two things will happen: the air pressure in the balloon will increase. the density of the air in the balloon will increase. Since density is mass over volume, and the mass stays constant, the rise in density means that the volume of the balloon decreases: pressure goes up; volume goes down.
