Q 3
3. A student performed an experiment to measure pressure and volume of a gas at constant temperature and noted the following :
Pressure (mm of Hg) | Volume (cm3) |
100 | 80 |
125 | x |
200 | 40 |
y | 32 |
Calculate the value of x and y.Which law was used in the calculations?Draw a suitable graph.
(Ans. x=64 cm3 , y=250 mm)
Dear student
Please find the solution to the asked query:
If P1= 100mmHg
V1= 80cm3
P2= 125mmHg
V2= x
Then
P1V1=P2V2
100.80 = 125.x
x =64cm3
Again
P3=200mmHg
V3=40cm3
P4=y
V4=32cm3
Thus
P3V3=P4V4
200.40 = y.32
y= 250cm3
This is in accordance with Boyles law.
