Question

the volume of a certain mass of a gas was found to be 800 CC when the pressure was 760 mm of HG if the pressure increases by 50% find the new volume of the gas assuming that temperature remains constant.

Answer 1

P1 = initial pressure, V1= initial volume,P2=final pressure and V2 = new volume
P1v1=P2v2
760*.8= 1140*v
v=.533l
v= 533cm^3

Answer 2

hello user,

>>> please refer the attached image for your answer.

•In the solution, Boyle's law is used , which States that temperature remaining constant, the volume of a given mass of dry gas is inversely proportional to the pressure of the gas.

ie,

V = 1/P [T= constant]
where,
V=volume of gas
P=Pressure of gas
T=temperature
