Two part question
The coefficient of linear expansion for some common materials are listed in the table. Material Suppose Mary would like to design an emergency overheating alarm using one of these materials. In her design, at room temperature (23.0 "C), a 6.01 cm long cylinder of the material will sit with one end against a wall and the other just barely touching a button. Once the heat causes the cylinder to lengthen by 0.0238 cm, the button will be...
