Gce Model Questions Vol1 2018 Physics Question 2
Practice objective / multiple choice question 2 from the 2018 Gce Model Questions Vol1 Physics examination.
A steel rod of length \(2.00\ \text{m}\) at \(20^{\circ}\text{C}\) expands by \(0.24\ \text{mm}\) when heated to an unknown temperature \(T_1\). When the rod is subsequently cooled from \(T_1\) to \(0^{\circ}\text{C}\) its length decreases by \(0.36\ \text{mm}\) relative to its length at \(T_1\). Assuming the coefficient of linear expansion \(\alpha\) is constant, determine the temperature \(T_1\) (in \(^{\circ}\text{C}\)).
