A thermal tap used in certain apparatus consists of a silica rod which fits tightly inside an Aluminium tube whose internal diameter is 8 mm at 0β . When the temperature is raised, the fit is no longer exact. Calculate what change in temperature is necessary to produce a channel whose cross-section is equal to that of a tube of 1 mm internal diameter. Ξ for silica = 8 Γ 10 β K β 1 , Ξ± for Aluminium = 26 Γ 10 β K β 1
