question 18

Multiple Choice

When the coefficient of linear expansion, $\alpha$ ,and the temperature change,T_f - T_i,are large,a length L_i of a solid substance expands in length to

• A)L_f = \(\alpha\)L_i(T_f - T_i).
• B)L_f = L_i[1 + \(\alpha\)(T_f - T_i)].
• C)L_f = L_i[1 + ln(\(\alpha\)(T_f - T_i))].
• D) \(L _ { f } = L _ { i } e ^ { \alpha \left( T _ { f } - T _ { 1 } \right) }\) .
• E) \(L _ { f } = L _ { i } \left[ 1 + e ^ { \alpha \left( T _ { f } - T _ { i } \right) } \right]\) .
