Question

A balloon has a volume of 6.5 L at a pressure of 0.98 atm. What is the volume of the balloon in liters if the atmospheric pressure is reduced to 0.36 atm?

Answer 1

Here we have , Two situations

Situation 1:

$V_1=6.5 L$

$P_1=0.98 atm$

Situation 2:

$P_2=0.36 atm$

$V_2=V_2(Let)$

Now we know that :

$P_1V_1=P_2V_2$

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

$V_2=\dfrac{0.98\times6.5}{0.36}=17.6944 L$
