Rhys has to sew a button on his shirt, but he nds that he can't thread the needle (Le. the cotton thread is too thick for the eye of the needle). After studying thermal physics, he decides he should heat the needle to make it expand so that the cotton thread can t through. Given that the thread was 8% too thick for the eye at room temperature (22C), to what temperature (in Celsius) should he bring the needle for the thread to t? (Given agree, = 10 x 10'6 Kt.)
