8.0 CALCULATIONS

Experiment 1
Given; V1 = 0.025 m3, V2 = 0.01237 m3

1. Pressure to atmosphere
P1 V 1=P2 V 2

( PT 1before ×V 1 ) + ( PT 2before ×V 2 )=( PT 1 after ×V 1 ) + ( PT 2after ×V 2 )


( 149.2× 0.025 ) + ( 103.3 ×0.01237 )=( 132.7 ×0.025 ) +(131.3× 0.01237)
5.01=4.94
The difference is 0.07 kpa⸱m3, so the Boyle’s law is verified

2. Atmospheric to vacuum
P1 V 1=P2 V 2

( PT 1before ×V 1 ) + ( PT 2before ×V 2 )=( PT 1 after ×V 1 ) + ( PT 2after ×V 2 )


( 104.6 ×0.025 )+ ( 53.4 × 0.01237 ) =( 90.6 ×0.025 ) +(89.3 ×0.01237)
3.28=3.37
The difference is 0.09 kpa⸱m3, so the Boyle’s law is verified

3. Pressurized to vacuum
P1 V 1=P2 V 2

( PT 1before ×V 1 ) + ( PT 2before ×V 2 )=( PT 1 after ×V 1 ) + ( PT 2after ×V 2 )


( 146.4 × 0.025 )+ ( 60.4 ×0.01237 )=( 115.3 × 0.025 )+(114 ×0.01237)
4.41=4.29
The difference is 0.12 kpa⸱m3, so the Boyle’s law is verified
