Answer:

The new volume of the ballon will be 13.345 L

Explanation:

Charles's Law consists of the relationship that exists between the volume and the temperature of a certain quantity of ideal gas, which is maintained at a constant pressure, by means of a constant of proportionality that is applied directly. For a given sum of gas at a constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases.

Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:

$\frac{V}{T}=k$

It is possible to assume that you have a certain volume of gas V1 that is at a temperature T1 at the beginning of the experiment. If you vary the volume of gas to a new value V2, then the temperature will change to T2, and it will be true:

$\frac{V1}{T1}=\frac{V2}{T2}$

In this case:

V1= 17 L
T1= 200 K
V2= ?
T2= 157 K

Replacing:

$\frac{17 L}{200 K} =\frac{V2}{157 K}$

Solving:

$V2= 157 K*\frac{17 L}{200 K}$

V2= 13.345 L

<u><em>The new volume of the ballon will be 13.345 L</em></u>
