87mL

Explanation:

Charles Law states that Volume and temperature are related according to the following equation:
$\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}$ $V_1/T_1 = V_2/T_2$
or $\frac{V_{1} T_{2}}{T_{1}} = V_{2}$ $(V_1T_2)/T_1 =V_2$

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

$T_{1}$ $T_1$ = $85^{o}$ $85^o$ C = 358K
$T_{2}$ $T_2$ = $25^{o}$ $25^o$ C = 298K (this is a standard)
$V_{1}$ $V_1$ = $105 c m^{3}$ $105cm^3$

$V_{2}$ $V_2$ = $\frac{105 c m^{3} \cdot 298 K}{358 K}$ $(105cm^3*298K)/(358K)$ = $87 c m^{3}$ $87cm^3$
