Question

if you have a 4.6 L of gas in a piston at a pressure of 1.2 atm and compress the gas unit it's volume is 2.6 L, what will the new pressure inside the piston be?

21.2 atm
2.12 atm
0.212 atm
0.00212 atm​

Answer 1

Answer:

The answer is 2.12 atm

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

Since we are finding the new pressure

$P_2 = \frac{P_1V_1}{V_2}$

So we have

$P_2 = \frac{4.6 \times 1.2}{2.6} = \frac{5.52}{2.6} \\ = 2.1230769...$

We have the final answer as

2.12 atm

Hope this helps you
