An air compressor is a device that pumps air particles into a tank. A particular air compressor adds air particles to its tank until the particle density of the inside air is 40 times that of the outside air. If the temperature inside the tank is the same as that outside, how does the pressure inside the tank compare to the pressure outside? Assume atmospheric pressure equal to 100,000 Pa. The number of significant digits is set to 3;
pressure in the tank is higher than the pressure outside the tank. If the atmospheric pressure is 100,000pa which is the pressure of air outside the tank, the pressure of air inside the tank=40*100000 Pa=4000000 Pa as the pressure inside the tank in 3 significant figures.
