Answers: 1
![V=V_{0} *\beta *DT\\where:\\V = final volume [m^{3} ]\\V_{0} = original volume [m^{3} ]\\\beta =34*10^-6[\frac{1}{C} ]\\DT= temperature difference [C]](/tpl/images/0432/6704/433da.png)
![V0 = \frac{4}{3} *\pi *r^{3} \\D = diameter = 0.125 [m]\\r = radius =0.0625[m]\\replacing\\V=\frac{4}{3} *\pi *(0.0625^{3} )\\V0=1.022[m^{3} ]\\](/tpl/images/0432/6704/a84ea.png)
![V=\frac{4}{3} *\pi *(0.0626)^{3} \\V=1.027*10^-3[m^{3} ]](/tpl/images/0432/6704/f74fb.png)
![(1.027*10^-3 - 1.022*10^-3)= 34*10^-6*DT\\DT= 0.14[C]](/tpl/images/0432/6704/ac995.png)
