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)?

1.in one challenge on the titan games, competitors have to lift 200 pounds up a long ramp. angel is able to move the weight in 42 seconds. anthony gets it done in only 38 seconds. which statement is true? angel has more power than anthony. angel does more work than anthony. anthony does more work than angel. anthony has more power than angel. 2.a mountain climber exerts 41,000 j of work to climb a cliff. how much power does the climber need if she wants to finish in only 500 seconds? power = work / time 20,500,000 watts 82 watts 0.0122 watts 41,500 watts 3.your family is moving to a new apartment. while lifting a box 83 joules of work is done to put the box on a truck, you exert an upward force of 75 n for 3 s. how much power is required to do this? (hint: you only need two of the 3 numbers given! ) power = work / time 249 watts 25 watts 2075 watts 27.7 watts
