Hint: To answer this question, we first need to understand what are vectors and quantities. We need to talk about the expansion of metal. The kinetic energy of a material's atoms causes its expansion (or contraction). When a substance is heated, the extra energy allows the atoms and molecules to travel around further and take up more space, or expand. This is true even for a solid like metal.
Complete answer:
Thermal expansion-Metals expand linearly as temperature rises, so the linear expansion is proportional to the material's length. The linear expansion coefficient is a material property that distinguishes the thermal expansion potential of various materials.
As in this case when we heat the metallic plate, the overall temperature of the sheet increases as discussed above about thermal expansion; the hole will also expand and so due to this phenomenon the diameter of the hole also increases.
As when a solid with a cavity is heated, the cavity expands in the same way as the rest of the object would if it were filled with the same material.
Therefore, the final solution is that the diameter of the hole expands.
Note: The coefficient of most steels is about 0.000011 per degree Celsius. In metric terms, this means that a one-meter-long unrestrained steel bar would lengthen by 11 millionths of a meter, or 11 thousandths of a millimeter, for every one-degree Celsius increase in temperature.
