Question

A balloon is filled with a 0, gas and has a volume of 179mL at 2.00 atm pressure. What will its volume be if thepressure is changed to 5.50 atm?A) 29.2 mLB) 65.1 mLC) 17.9 mLD) 83.0 ml

Answer 1

In this case, we can use the Boyle's law to solve this problem:

`P1\cdot v1=P2\cdot v2`

We already know the values of P1, v1 and P2 and we have to find v2. Replace for the given values and solve for v2:

`\begin{gathered} 179ml\cdot2.00atm=5.50atm\cdot v2 \\ v2=(179ml\cdot2.00atm)/(5.50atm) \\ v2=65.1ml \end{gathered}`

The correct answer is B) 65.1ml.
