Aluminum rivets used in airplane construction are made slightlylarger than the rivet holes and cooled by "dry ice" (solid CO2)before being driven. If the diameter of a hole is 4.460 mm , whatshould be the diameter of a rivet at 23.0 °C, if its diameter is toequal that of the hole when the rivet is cooled to -79.5 °C, thetemperature of dry ice? Assume that the expansion coefficient ofaluminum is 2.4×10-5(°C)-1 and remains constant
