Which of the following properties of a long steel bar would alter if the bar were melted, recast into a cube and allowed to cool to its original temperature?
Answer Details
The property that would alter if a long steel bar were melted, recast into a cube and allowed to cool to its original temperature is its volume. When the steel bar is melted and recast into a cube, the volume of the cube will be different from the volume of the original steel bar. This is because the shape of the cube is different from that of the bar. However, if the cube is allowed to cool to its original temperature, its volume will be the same as that of the original bar. The other properties such as density, specific heat capacity and electrical resistance will remain unchanged since they are intrinsic properties of the material and do not depend on the shape of the object.
