Q1. The supersonic aircraft Concorde has a length of 63.0 rm{m} when sitting on the ground on a typical day when the temperature is 16.0rm{^{circ}C}. The Concorde is primarily made of aluminium. In flight at twice the speed of sound, friction with the air warms the Concorde's skin and causes the aircraft to lengthen by 20.0 rm{cm}. (The passenger cabin is on rollers, so the airplane expands around the passenger cabin.)

Take the coefficient of linear expansion for aluminium to be alpha =2.40×10-5/rm{^{circ}C}.What is the temperature T of the Concorde's skin in flight?

Q2. Heat is extracted from a certain quantity of steam at 100 degrees celsius. Thus the steam changes into ice at 0 degrees celsius. If this energy were used to accelerate the ice from rest, what would be the linear speed of the ice?
