A sample of gas in a balloon has an initial temperature of 23 ∘C and a volume of 1.09×103 L . If the temperature changes to 59 ∘C , and there is no change of pressure or amount of gas, what is the new volume, V2, of the gas?

Answer:

[tex]1.22\cdot 10^3 L[/tex]

Explanation:

We can solve the problem by using Charle's law, which states that for a gas kept at constant pressure, the volume of the gas is directly proportional to its temperature:

[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]

where here we have

[tex]V_1 = 1.09\cdot 10^3 L[/tex] is the initial volume

[tex]T_1 = 23^{\circ}+ 273 = 296 K[/tex] is the initial temperature

[tex]V_2[/tex] is the final volume

[tex]T_2 = 59^{\circ}+ 273 =332 K[/tex] is the final temperature

Solving for V2, we find

[tex]V_2 = \frac{V_1 T_2}{T_1}=\frac{(1.09 \cdot 10^3 L)(332 K)}{296 K}=1.22\cdot 10^3 L[/tex]
