Due to the fluid above the region the downward force acting on this region is equal to the pressure times the area of contact. It states the pressure of a gas is inversely proportional to the volume of the gas at a constant temperature and for a fixed amount of the gas. This equation is derived from four empirical gas laws Charles Boyles Gay.
As with the other gas laws we can also say that P V T n is equal to a constant.
P V text constant at constant n and T If either volume or pressure changes while amount and temperature stay the same then the other property must change so that the product of the two properties still equals that same constant. Volume is the amount of space that an object takes up and may be measured in liters gallons or cubic meters. The blood pressure equation including the stroke volume equation and the cardiac output equation tells the doctor how stable or critical patients are. This means that when we hold amount and volume of gas constant the pressure of gas will increase as its temperature increase.
