What is the average atmospheric pressure?Question:What is the average atmospheric pressure?Air Pressure:Earth's atmosphere is somewhat unique. The troposphere is 78% nitrogen, 21% oxygen, and varying quantities of several other gasses with a varying degree of water vapor and carbon dioxide depending...
What is air pressure?
What is the average atmospheric pressure? What is the difference between sea level and elevation? Is sea level pressure the same as air pressure? What is the normal range for barometric pressure? What is eustatic sea level? How much pressure is there in air currents?
To solve the problem of finding the minimum pressure required to compress 460 dm³ of air at 2 bar to 230 dm³ at 30°C, we can use Boyle's Law, which states that for a given mass of gas at constant temperature, the product of pressure and volume
