Neco Model Questions Vol1 2019 Physics Question 31
Practice objective / multiple choice question 31 from the 2019 Neco Model Questions Vol1 Physics examination.
A steel rod of length \(2.00\,\text{m}\) at \(20^{\circ}\text{C}\) expands linearly with a constant coefficient of linear expansion \(\alpha\). When heated to \(120^{\circ}\text{C}\) its length becomes \(2.06\,\text{m}\). The rod is then placed in a freezer until its length reduces to \(1.98\,\text{m}\). Assuming \(\alpha\) remains unchanged, determine the temperature of the freezer in \(^{\circ}\text{C}\).
