Question

Part A: Increasing Piston Displacement (L)

L (cm)	Pg (atm)
7.0	1.6
8.0	1.34
9.0	1.2
10.0	1.1
11.0	0.10
12.0	0.9
13.0	0.8
14.0	0.72
15.0	0.69
16.0	0.6
17.0	0.59
18.0	0.52
19.0	0.5
20.0	0.49
21.0	0.45
22.0	0.35
23.0	0.3
24.0 25.0	0.3 0.29

1. Calculate the product of the pressure P and length L for every row in both data tables.

2. Calculate the deviation for each value of PL.

Part B: Decreasing Piston Displacement (L)

L (cm)	Pg (atm)
25.0	0.29
24.0	0.3
23.0	0.3
22.0	0.32
21.0	0.45
20.0	0.49
19.0	0.5
18.0	0.51
17.0	0.58
16.0	0.61
15.0	0.67
14.0	0.71
13.0	0.79
12.0	0.85
11.0	0.95
10.0	1.05
9.0	1.2
8.0	1.35
7.0	1.6

Answer 1

ihave calculated product by just multiplying the pressure and length values
