87mL

#### Explanation:

Charles Law states that Volume and temperature are related according to the following equation:
${V}_{1} / {T}_{1} = {V}_{2} / {T}_{2}$
or $\frac{{V}_{1} {T}_{2}}{T} _ 1 = {V}_{2}$

**note that temperature must use the Unit Kelvin (can't have a negative volume!) and not Celsius.

${T}_{1}$=${85}^{o}$C = 358K
${T}_{2}$=${25}^{o}$C = 298K (this is a standard)
${V}_{1}$=$105 c {m}^{3}$

${V}_{2}$= $\frac{105 c {m}^{3} \cdot 298 K}{358 K}$ = $87 c {m}^{3}$
