1) List the known and unknown values

Final conditions

Volume: 7.8 L

Temperature: 100 K

Initial conditions

Temperature: 435 K

Unknown

Volume:

2) set the equation

Charles' law


(V1)/(T1)=(V2)/(T2)

3) Plug in the known values


(V1)/(435K)=(7.8L)/(100K)
V1=\frac{7.8\text{ }L}{100\text{ }K}*435\text{ }K=33.93\text{ }L
