Pls help :( 5. Robert Boyle was an Anglo Irish physicist and inventor. During the 17" century
he studied the behaviour of gases
In one of his experiments he used a fixed mass of gas and started to apply pressure to
decrease its volume. He observed what happened to the gas pressure and noted the
valnes obtained in the following table.
Pressure, P (kPa)
20
30
40
SO
60
Volume, V (em)
250
166.67
125
100
83.33
1/Volume, 1/V (1/em')
0.04
L.
Complete the inble above.

ii. Draw a graph of 1/Volume on the x-axis against Pressure on the y-axis.

iii. What is the relation between Pressure and 1/Volume?

iv. Explain what would happen to the Pressure when the Volume is halved,

. Explain in terms of molecular motion the cause for this change in pressure when the
volume of a fixed mass of pas is halved

vi. What should be assumed in part (v)?
