Answer :
Answer: Initial volume = 18 L
Calculations:
We are given -
• Volume 1 (V1) = ?
,• Temperature (T1) = 120K
,• Volume 2(V2) = 45L
,• Temperature (T2) = 300K
We can use Charles law equation to solve for initial volume :
[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]Replacing the given parameters into Charles law equation, we get that V1 is :
[tex]\begin{gathered} V_1=\frac{V_2}{T_2}\cdot T_1 \\ \text{ =}\frac{45L}{300K\text{ }}\cdot120K\text{ } \\ \text{ = 18L} \end{gathered}[/tex]
