关于气压
一个锅炉内部密度为外部空气的15倍,温度与外部一样.内外气压对比.假设大气压为100000 Pa
P=____ Pa
原题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 15 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.

由PV=nRT n=ρv/m
P1V=ρ1VRT/m
P2V=ρ2VRT/m
P2/P1=ρ2/ρ1
P2=15P1=1.5x10^6pa
