Answer:
The pressure P₂ = 30 pounds when volume is 140 cubic inches
Step-by-step explanation:
We are given
Pressure P₁ = 35 pounds
Volume V₁ = 120 cubic inches
Volume V₂ = 140 cubic inches
We need to find Pressure P₂
The formula used will be: [tex]V_1P_1=V_2P_2[/tex]
Putting values and finding P₂
[tex]V_1P_1=V_2P_2\\120\times 35=140\times P_2\\4200=140\times P_2\\P_2=\frac{4200}{140} \\P_2=30 \ pounds[/tex]
So, the pressure P₂ = 30 pounds when volume is 140 cubic inches
