Final answer:
Air pressure per cubic centimeter varies, but atmospheric pressure at sea level is about 101 kPa or 14.7 psi. Pressure is force per unit area, measured in pascals, and can be assessed with a barometer or manometer.
Step-by-step explanation:
The pressure that air exerts per cubic centimeter is dependent on several factors, including the number of gas molecules in that volume and the temperature of the gas. In physics, pressure is defined as the force exerted per unit area (P = F/A).
The SI unit of pressure is the pascal (Pa), which is equivalent to one newton per square meter (N/m²). Earth's atmospheric pressure at sea level, often referred to as 1 atmosphere, is approximately 101 kPa or 14.7 psi (pounds per square inch).
However, this value will change according to the altitude and weather conditions. To understand the pressure exerted by a particular volume of air, one would typically use a device such as a barometer or manometer to measure it. The concept of pressure is crucial in understanding the behavior of gases and is fundamental to many aspects of science and engineering.
