A student performed an experiment to measure
pressure and volume of a gas at constant
temperature and noted the following:
Pressure (mm of Hg)
100
125
200
y
Volume (cm³)
80
x
40
32
Calculate the value of x and y. Which law was
used in the calculations ? Draw graphs to
show :
(i) volume plotted against pressure.
(ii) PV plotted against pressure
X
Pls answer fast

Answer:
Using ideal gas law, PV = nRT (cons.)
Hence taking P1V1 = P2V2 (Assuming to be ideal condition as for measurement)
So X = 60cm³
Y = 250 mm of Hg
(Refer attachments for calculation)
i) Invert graph (Refer attachments)
ii) Parallel to the pressure axis (Refer to the attachments)
hope this will help you
