Question

An aluminium baseball has a coefficient of volume expansion of 69×19-⁶°C-¹, the bat has a length of 0.86m at a temperature of 25°C. When the temperature of the bat is increased,the bat expands by 0.00016m. Determine the final temperature of the bat

Answer 1

$t_2=t_1+\frac{∆l}{\beta l}=27.7°C.$
