Question

800cc of gas was collected at 650 mm pressure ,at what pressure would the volume of the gas be reduced by 49 of its original volume .the temperature remaining constant

Answer 1

Answer:

According to Boyle's law P1V1=P2V2

⇒P1=650 mm,V1=800 cm3,

V2=Volume reduced by 40%. Remaining volume is 60% of its original volume=100800×60=480cm3.  

⇒P2=480650×800=1083 mm
