When the temperature is constant.the pressure of a given mass varies inversely as the volume.Given that the pressure is 8kPa when the volume is 150cm^3,the pressure if the volume is 100cm^3 is
A.16kPa B.18kPa C.24kPa D.24kPa
先翻译.再 .

当温度恒定不变,特定质量的压力与容积成反比.当容积为150cm³时,压力是8kpa.则当容积式100cm³时,压力是多少?
怎么两个相等的答案?
应该是:150*8=100*F压 F压=12kpa
