a thin metal rod expands 1.5 mm when its temperature is increased by 2 degrees celcius. If an identical rod of the same material, except twice as long, also has its temperature increased by 2 degrees celcius, it will expand to what length?
 
Your answer is 3.0 mm. This is because for moderate temperature changes delta L is directly proportional to delta T.
